Late last week, I noticed a spike in what we might think of as a certain financial index. It wasn’t the trading in a financial instrument per se, but in the online traffic in a column I had written in December 2013. The column examined the recent crash in the price of bitcoins, which had plummeted to $600 from $1,200 in just two days. The headline read:
Bitcoin mining is the process of adding transaction records to Bitcoin’s public ledger of past transactions. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place.
By mining, you can earn cryptocurrency without having to put down money for it. That said, you certainly don’t have to be a miner to own crypto. You can also buy crypto using fiat currency (USD, EUR, JPY, etc); you can trade it on an exchange like Bitstamp using other crypto (example: Using Ethereum or NEO to buy Bitcoin); you even can earn it by playing video games or by publishing blogposts on platforms that pay its users in crypto. An example of the latter is Steemit, which is kind of like Medium except that users can reward bloggers by paying them in a proprietary cryptocurrency called Steem. Steem can then be traded elsewhere for Bitcoin.

Electricity, it so happens, is one thing most Venezuelans can afford: Under the socialist regime of President Nicolás Maduro, power is so heavily subsidized that it is practically free. A person running several bitcoin miners can clear $500 a month. That’s a small fortune in Venezuela today, enough to feed a family of four and purchase vital goods—baby diapers, say, or insulin—online. (Most web retailers don’t ship directly to Venezuela, but some Florida-based delivery services do.)
Coinbase, for example, has been such a popular bitcoin investment app that its CEO posted to the company’s blog last week a warning that the sudden influx “does create extreme volatility and stress on our systems,” which can create a lag for users. The Chicago Board Options Exchange, on which the first bitcoin futures trading took place this week, warned that a flood of traffic ahead of the launch was slowing its site.
Bitcoins per Block – Each time a mathematical problem is solved, a constant amount of Bitcoins are created. The number of Bitcoins generated per block starts at 50 and is halved every 210,000 blocks (about four years). The current number of Bitcoins awarded per block is 12.5. The last block halving occurred on July 2016 and the next one will be in 2020.
Coinbase, for example, has an Instant Buy option but you must use a credit or debit card so the transaction can be authenticated instantly and they charge 3.99% per purchase, rather than the usual 1.49%.
It must also be borne in mind that entrusting funds to any exchange carries some measure of custodial risk. This is true whether the exchange allows direct trading of Bitcoin or offers Bitcoin derivative products. Always investigate an exchange’s reputation and policies before entrusting funds to them. Somewhat counter-intuitively, exchanges with higher margin requirements are often the better choice as they’re better protected against black swan market events. Among the top tier of CFD platforms which allow Bitcoin trading, such as Plus500 and AvaTrade, you’ll find margin requirements (and fees) very similar.
Please note that virtual currency is a digital representation of value that functions as a medium of exchange, a unit of account, or a store of value, but it does not have legal tender status. Virtual currencies are sometimes exchanged for U.S. dollars or other currencies around the world, but they are not currently backed nor supported by any government or central bank. Their value is completely derived by market forces of supply and demand, and they are more volatile than traditional fiat currencies. Profits and losses related to this volatility are amplified in margined futures contracts.
It turned out they were there for the winning side. The federal district judge ruled that Klein should not be imprisoned. He was instead given five years probation, a $10,000 fine and 120 hours of community service (as well as a demand to pay the $2,122.68 he earned back to the IRS as restitution). “I was giving out hugs like candy,” Klein recalls. His friends had a beer waiting for him at a local bar after it was all over and clapped when he walked in. The Kleins were also able to recoup about half of the money they scraped together for a legal retainer by avoiding a trial.
To complicate mining even further, something called the Bitcoin Difficulty is implemented in the process. It is a measure of how difficult it is to find a new block compared to the easiest it can ever be.
“While [Montroll] admitted that the Balance Statement was the product of his manual intervention in the WeExchange system, he claimed to have discovered the success of the Exploit only after the SEC had asked him about it during his first day of testimony and to have no knowledge of the chat with Person-1,” the Department said.

Of course, Coinbase isn’t your only option if you want to buy Bitcoins in the US. There are countless other sites, some of which charge lower fees than Coinbase so it’s worth considering other options.
Bitcoin Cash: You might want a paper bag for this one. Bitcoin Cash peaked the day after Bitcoin, but its drop has been even more staggering, tumbling 71% since Dec. 19. Your $1,000 is worth just $290 now. If you’d invested that amount just one day later, though, it’d be worth just $224.
So, what is Bitcoin mining? It’s the process by which transactions conducted with Bitcoin are added to the public ledger. It’s a method of interacting with the blockchain that Bitcoin is built upon and for those that take part in the computationally complicated activity, there are Bitcoin tokens to be earned.
In a pool, you are given smaller and easier algorithms to solve and all of your combined work will make you more likely to solve the bigger algorithm and earn Bitcoins that are spread out throughout the pool based on your contribution. Basically, you will make a more consistent amount of and will be more likely to receive a good return on your investment.
What separated these survivors from the quitters and the double-downers, Carlson concluded, was simply the price of electricity. Survivors either lived in or had moved to places like China or Iceland or Venezuela, where electricity was cheap enough for bitcoin to be profitable. Carlson knew that if he could find a place where the power wasn’t just cheap, but really cheap, he’d be able to mine bitcoin both profitably and on an industrial scale.
