Two men and a woman had lost track of days as they survived on a diet of coconuts, conchs and rats for more than a month after they were cast away on a deserted island between Florida and Cuba.
US Coast Guard officials said the trio from Cuba told them their boat had capsized in rough waters and they were able to swim to Anguilla Cay, where they spent 33 days before they were spotted and rescued.

As power struggle unfolds, the ANC provincial chair says infighting among factions has the potential to destroy the governing party in the province.
Fed chair calls on legislators and the private sector to support workers in speech to Economic Club of New York. The Twenty20 stand-in captain suffered heart palpitations when he had the viral infection two months ago. The ANC is postponing all its upcoming conferences, including its midterm conference, the national general council NGC , as the country deals with the spread of the Covid pandemic.
Ramaphosa addressed the media as ANC president less than 24 hours after he declared a national state of disaster. The president on Sunday announced sweeping measures to help contain the spread of the virus, which included travel restrictions on foreigners from hard-hit countries, a ban on mass gatherings of more than people and the closure of schools. The DA has also announced that it has postponed its policy conference, which was scheduled to take place on April 4 and 5.
Ramaphosa said on Monday that just because conferences were cancelled it did not mean that the ANC was no longer working. He said the party would conduct door-to-door visits in communities to educate people about the Covid virus and would distribute pamphlets, which had to be done physically. If there is any time the ANC must get down to work, now is the time. Ramaphosa, as ANC president, said he will be meeting with all political parties in Cape Town to discuss how all parties can approach the virus and the crisis the country is facing in a non-political way and work together.
Meanwhile, the IFP announced it would be cancelling its 45th anniversary celebration set for Saturday. Would you like to comment on this article or view other readers' comments? Subscribe Sign In.

Cooling Fans — Bitcoin hardware can easily overheat and stop working. Buy a sufficient amount of cooling fans to keep your hardware working. Backup generators — You may want generators as a backup in case your main source of electricity goes down. You can find Bitcoin mining equipment for sale on eBay.
Bitcoin is based on blockchain technology, a decentralized platform which takes power away from a central authority and gives it to the average person. Sensitive information is stored on the blockchain rather than large data centers, and is cryptographically secured. A vast amount of people, known as miners, all work together to validate the network, instead of just one person or government. In the beginning, CPU s were used to solve cryptographic hash functions , until miners discovered that GPU s were far better equipped for mining.
As block difficulty increased, miners turned primarily to GPUs. Their hashrates are significantly higher than anything GPUs are capable of. With stellar performance comes a high price tag — the best ASIC chips will run you a few thousand dollars each. Upon creation, Bitcoin blocks were confirmed by the average person using their desktop — once ASICs hit the market, things changed. ASIC developers, including Bitmain, granted early access to large mining cartels rather than the average person.
Nowadays, a large majority of Bitcoin mining takes place in China where electricity is cheap. Thousands of ASICs all mine simultaneously in a mining farm large warehouse. Unfortunately, Bitcoin is no longer as decentralized as it was once intended to be. Buy Antminer S7 on eBay. The S7 is also a popular choice among hobbyist miners for its reasonable price and strong performance. The strong metal casing features a tongue and groove system which allows for the neat arrangement of multiple miners.
The APW3 requires a minimum Volts to function and does not ship with the necessary 16A power cord. While an integral PSU makes for a compact and convenient miner, there are few other reasons to recommend such a setup.
The S7-LN also excludes a cord. Note: Before you buy an Antminer S7 make sure you already have Bitcoin mining software and a Bitcoin mining pool. These prices can be expected to fall further as the S9 and other superior mining hardware becomes the new standard.
With careful tweaking, it may be possible to profit from an S7 even at 15c power. The same calculations adjusted for the Hash Rate and Power consumption of the S7-LN produces slightly more encouraging results:. Naturally, the hotter the environment, the more energy the fan s will consume to cool the unit.
The S7 is twice as efficient as the S5 at converting all this energy into bitcoins; it requires a modest 0. Setting them up via the MinerLink GUI is a simple process, requiring only your mining pool credentials to begin mining. The units will automatically begin hashing upon powering up, which can be helpful in the event of power failure. S7 connectivity is via Ethernet only. They are both cooled by dual fans. A dry basement is an ideal location. This peak was reached on May 24 th Such tremendous growth has been spurred by major investment into Bitcoin mining technology and operations.
Profits have accumulated where mining is most profitable China , with the result that several competing operations eg. KNC have been forced out of the industry. We have tried to calculate the amount of money that the Chinese have invested in mining, we estimate it to be in the hundreds of millions of dollars. Even with free electricity we cannot see how they will ever get this money back.
The same Chinese competitive advantage has been doubly effective at squeezing the profit-dependent hobbyist miner from the market. With the block reward halving looming, the profitability of all but the most efficient operations will likely be challenged.
Given that profits derived from the current generation of mining hardware are dwindling and will likely reach negative returns post-halving:. Can the new S9 change the game for smaller and hobby miners and restore their lost profitability? Note: Before you buy an Antminer S9 make sure you already have Bitcoin mining software and a Bitcoin mining pool.
The first batch of S9s will be available for order directly from Bitmain from the 12 th of June. However, the lower your electricity costs, the better your odds of the miner paying for itself within a reasonable timeframe. Judging value in this space is a complicated exercise, although it would appear that nothing vastly technologically-superior to the S9 is likely to be released in the near future. The release cycle of a new generation of mining hardware every few months is likely to decelerate from this point on, as manufacturers have transitioned to cutting-edge 16 and 14nm designs.
The on-going miniaturisation of semiconductors allows ever greater computing power and electrical efficiency, but the process cannot continue forever with the current technology. The 16 nm fabrication process used in the manufacture of the S9 is a major improvement upon the 28 nm design common to other modern mining devices.
Although a 10nm process is on the horizon for , further increases beyond that remain theoretical. Further, the design and manufacture of any 10nm Bitcoin mining hardware is likely to take at least a year. Our guide on the best bitcoin wallets will help you get one fast and for free. Read it here!
The good news is that existing power supplies, at least those of sufficient wattage, are fully compatible with the S9. A total of chips, spread over 3 circuit boards, are combined to achieve this phenomenal hashrate. Note that Power Cost will be specific to your location and that Difficulty changes every 2 weeks, usually to the upside….
Your Pool Fees will be determined by your mining pool; although the S9 is plenty powerful, a single unit is highly unlikely to find any blocks when solo-mining. Of course, such impressive results assume all factors stay constant which is hugely improbable in the ever-changing world of Bitcoin!
The cutting-edge manufacturing process is what makes the S9 the most electrically-efficient mining device to date. It uses a mere 0. The S9 consumes about W more than the S7. Apart from the power supply, the S9 is a self-contained unit. It requires no connection to another computer to interface with other Bitcoin nodes. The S9 performs reliably in any well-ventilated space, whether a single or several unit s kept in a spare room or hundreds to thousands of units in a large mining center.
On the other hand, the halving could bring about a higher Bitcoin price and reduced competition, increasing profitability. It is likely to remain profitable for far longer than previous generations of ASIC miner, although ROI cannot be guaranteed given the inherent unpredictability of Bitcoin mining.
Bitmain is regarded as one of the most influential companies in the ASIC mining industry. Halong Mining is no longer around. It seems they could not compete with the already established ASIC manufacturers, most likely because they could never fill their orders and get the partsd they needed to produce enough miners to make money. The DragonMint W power supply is strongly recommended, though not mandatory.
Each miner requires its own individual power supply. Professional mining hardware runs optimally at V, hence why mining farms step down their own electricity supply to V. In any case, it would be a good idea to buy the DragonMint power supply. These PSUs will get the job done, but they are not ideal for optimum mining performance.
Consuming merely 0. Keep in mind that exact power consumptions vary, especially depending on which power supply you are using. Take a look at the projected mining profitability of a single miner :. The Antminer R4 hashes at up to 8. BitFury was the first company to release 16nm chips.
As the saying goes nothing good comes cheap. With all the awesome features that come with the Antminer R4 you would expect its price to be high. Its price is among its cons because this may be too high for the average hobby miner. Our decision to move Bitcoin from Los Angeles to Miami was not an easy one, but given the circumstances regarding availability in the State of California, we feel the move is necessary this year.

Less computing power means the difficulty level decreases. To get a sense of just how much computing power is involved, when Bitcoin launched in the initial difficulty level was one. As of Nov. All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a GPU graphics processing unit or, more realistically, an application-specific integrated circuit ASIC.
The photo below is a makeshift, home-made mining machine. The graphics cards are those rectangular blocks with whirring fans. Note the sandwich twist-ties holding the graphics cards to the metal pole. This is probably not the most efficient way to mine, and as you can guess, many miners are in it as much for the fun and challenge as for the money. The ins and outs of bitcoin mining can be difficult to understand as is.
And there is no limit to how many guesses they get. Let's say I'm thinking of the number There is no "extra credit" for Friend B, even though B's answer was closer to the target answer of Now imagine that I pose the "guess what number I'm thinking of" question, but I'm not asking just three friends, and I'm not thinking of a number between 1 and Rather, I'm asking millions of would-be miners and I'm thinking of a digit hexadecimal number.
Now you see that it's going to be extremely hard to guess the right answer. In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day, there can only be one winning answer. Typically, it is the miner who has done the most work or, in other words, the one that verifies the most transactions. The losing block then becomes an " orphan block. Miners who successfully solve the hash problem but who haven't verified the most transactions are not rewarded with bitcoin.
Well, here is an example of such a number:. The number above has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of the alphabet. Why is that? To understand what these letters are doing in the middle of numbers, let's unpack the word "hexadecimal.
As you know, we use the "decimal" system, which means it is base This, in turn, means that every digit of a multi-digit number has 10 possibilities, zero through nine. In a hexadecimal system, each digit has 16 possibilities. But our numeric system only offers 10 ways of representing numbers zero through nine. That's why you have to stick letters in, specifically letters a, b, c, d, e, and f. If you are mining bitcoin, you do not need to calculate the total value of that digit number the hash.
I repeat: You do not need to calculate the total value of a hash. Remember that ELI5 analogy, where I wrote the number 19 on a piece of paper and put it in a sealed envelope? In bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash. What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep talking about.
In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is bits. In theory, you could achieve the same goal by rolling a sided die 64 times to arrive at random numbers, but why on earth would you want to do that? The screenshot below, taken from the site Blockchain. You are looking at a summary of everything that happened when block was mined. The nonce that generated the "winning" hash was The target hash is shown on top.
The term "Relayed by Antpool" refers to the fact that this particular block was completed by AntPool, one of the more successful mining pools more about mining pools below. As you see here, their contribution to the Bitcoin community is that they confirmed transactions for this block. If you really want to see all of those transactions for this block, go to this page and scroll down to the heading "Transactions. All target hashes begin with zeros—at least eight zeros and up to 63 zeros.
There is no minimum target, but there is a maximum target set by the Bitcoin Protocol. No target can be greater than this number:. Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:. You'd have to get a fast mining rig, or, more realistically, join a mining pool—a group of coin miners who combine their computing power and split the mined bitcoin. Mining pools are comparable to those Powerball clubs whose members buy lottery tickets en masse and agree to share any winnings.
A disproportionately large number of blocks are mined by pools rather than by individual miners. In other words, it's literally just a numbers game. You cannot guess the pattern or make a prediction based on previous target hashes. Not great odds if you're working on your own, even with a tremendously powerful mining rig.
Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem. They must also consider the significant amount of electrical power mining rigs utilize in generating vast quantities of nonces in search of the solution.
All told, bitcoin mining is largely unprofitable for most individual miners as of this writing. Source: Cryptocompare. Mining rewards are paid to the miner who discovers a solution to the puzzle first, and the probability that a participant will be the one to discover the solution is equal to the portion of the total mining power on the network. Participants with a small percentage of the mining power stand a very small chance of discovering the next block on their own.
For instance, a mining card that one could purchase for a couple of thousand dollars would represent less than 0. With such a small chance at finding the next block, it could be a long time before that miner finds a block, and the difficulty going up makes things even worse. The miner may never recoup their investment.
The answer to this problem is mining pools. By working together in a pool and sharing the payouts among all participants, miners can get a steady flow of bitcoin starting the day they activate their miner. As mentioned above, the easiest way to acquire bitcoin is to simply buy it on one of the many exchanges. Alternately, you can always leverage the "pickaxe strategy. Or, to put it in modern terms, invest in the companies that manufacture those pickaxes.
In a cryptocurrency context, the pickaxe equivalent would be a company that manufactures equipment used for Bitcoin mining. The legality of Bitcoin mining depends entirely on your geographic location. The concept of Bitcoin can threaten the dominance of fiat currencies and government control over the financial markets. For this reason, Bitcoin is completely illegal in certain places. Bitcoin ownership and mining are legal in more countries than not.
The risks of mining are that of financial risk and a regulatory one. As mentioned, Bitcoin mining, and mining in general, is a financial risk. One could go through all the effort of purchasing hundreds or thousands of dollars worth of mining equipment only to have no return on their investment. That said, this risk can be mitigated by joining mining pools. If you are considering mining and live in an area that it is prohibited you should reconsider. It may also be a good idea to research your countries regulation and overall sentiment towards cryptocurrency before investing in mining equipment.
