Bridges is awaiting sentencing in December Superintendent of New York State Department of Financial Services, Benjamin Lawsky, released a set of customized rules meant to regulate Bitcoin and digital currency businesses that serve customers located in New York state. These regulations are the first ever directly targeted at digital currency businesses.
According to the regulations, digital currency companies that serve NY customers must apply for a "BitLicense" within 45 days or be considered in "breach of the law".

This explainer is meant to clarify some of the fundamental concepts and provide answers to some basic bitcoin questions. Bitcoin was invented in by a person or group who called himself Satoshi Nakamoto. Check out the New Yorker's great profile of Nakamoto from Simply put, bitcoin is a digital currency.
No bills to print or coins to mint. It's decentralized -- there's no government, institution like a bank or other authority that controls it. And it isn't issued from the top down like traditional currency; rather, bitcoin is "mined" by powerful computers connected to the internet. A person or group, or company mines bitcoin by doing a combination of advanced math and record-keeping. Here's how it works.
When someone sends a bitcoin to someone else, the network records that transaction, and all of the others made over a certain period of time, in a "block.
These blocks are known, collectively, as the "blockchain" -- an eternal, openly accessible record of all the transactions that have ever been made. Using specialized software and increasingly powerful and energy-intensive hardware, miners convert these blocks into sequences of code, known as a "hash. It's like thousands of chefs feverishly racing to prepare a new, extremely complicated dish -- and only the first one to serve up a perfect version of it ends up getting paid.
When a new hash is generated, it's placed at the end of the blockchain, which is then publicly updated and propagated. For his or her trouble, the miner currently gets Note that the amount of awarded bitcoins decreases over time. Ultimately, the value of a bitcoin is determined by what people will pay for it.
In this way, there's a similarity to how stocks are priced. The protocol established by Satoshi Nakamoto dictates that only 21 million bitcoins can ever be mined -- about 12 million have been mined so far -- so there is a limited supply, like with gold and other precious metals, but no real intrinsic value. There are numerous mathematical and economic theories about why Nakamoto chose the number 21 million.
This makes bitcoin different from stocks, which usually have some relationship to a company's actual or potential earnings.
Without a government or central authority at the helm, controlling supply, "value" is totally open to interpretation. This process of "price discovery," the primary driver of volatility in bitcoin's price, also invites speculation don't mortgage your house to buy bitcoin and manipulation hence the recent talk of tulips and bubbles.
Bitcoin has made Satoshi Nakamoto a billionaire many times over, at least on paper. It's minted plenty of millionaires among the technological pioneers, investors and early bitcoin miners.
