Needless to say, Bitcoin’s place as an alternative digital asset among cryptocurrencies has become entrenched, despite likely headwinds it will continue to face as it evolves further. The U.S. Securities and Exchange Commission (SEC) announced in early August 2017 that certain Initial Coin Offerings (ICOs) – which use cryptocurrencies for financing – would be regulated as securities.
Central to the appeal and function of Bitcoin is the blockchain technology it uses to store an online ledger of all the transactions that have ever been conducted using bitcoins, providing a data structure for this ledger that is exposed to a limited threat from hackers and can be copied across all computers running Bitcoin software. Every new block generated must be verified by the ledgers of each user on the market, making it almost impossible to forge transaction histories. Many experts see this blockchain as having important uses in technologies such as online voting and crowdfunding, and major financial institutions such as JPMorgan Chase see potential in cryptocurrencies to lower transaction costs by making payment processing more efficient. However, because cryptocurrencies are virtual and do not have a central repository, a digital cryptocurrency balance can be wiped out by a computer crash if a backup copy of the holdings does not exist, or if somebody simply loses their private keys.
An initial coin offering (ICO) is a controversial means of raising funds for a new cryptocurrency venture. An ICO may be used by startups with the intention of avoiding regulation. However, securities regulators in many jurisdictions, including in the U.S., and Canada have indicated that if a coin or token is an "investment contract" (e.g., under the Howey test, i.e., an investment of money with a reasonable expectation of profit based significantly on the entrepreneurial or managerial efforts of others), it is a security and is subject to securities regulation. In an ICO campaign, a percentage of the cryptocurrency (usually in the form of "tokens") is sold to early backers of the project in exchange for legal tender or other cryptocurrencies, often bitcoin or ether.[47][48][49]
If you happen to own a business and if you’re looking for potential new customers, accepting cryptocurrencies as a form of payment may be a solution for you. The interest in cryptocurrencies has never been higher and it’s only going to increase. Along with the growing interest, also grows the number of crypto-ATMs located around the world. Coin ATM Radar currently lists almost 1,800 ATMs in 58 countries.
Within a cryptocurrency network, only miners can confirm transactions by solving a cryptographic puzzle. They take transactions, mark them as legitimate and spread them across the network. Afterwards, every node of the network adds it to its database. Once the transaction is confirmed it becomes unforgeable and irreversible and a miner receives a reward, plus the transaction fees.
Gray Box Ive opened a few short positions in tether, eventually it will probably crash (which I think will precipitate the proper BTC bottom of this cycle) and until then its not going to past its $1 peg, So huge downside and no upside.  Very hard to predict when it will happen other than it will be caused by regulatory action so will probably happen on a weekday. I don't use it as a settlement anymore, its the main reason i only dabble in alts these days(most of my volume is on kraken trading against proper USD/EURO/YEN pairs.- If tether crashes, btc will crash and most exchanges will offer to refuge. Oh it will be fun to watch but horrific for those trapped.

In 1998, Wei Dai published a description of "b-money", characterized as an anonymous, distributed electronic cash system.[12] Shortly thereafter, Nick Szabo described bit gold.[13] Like bitcoin and other cryptocurrencies that would follow it, bit gold (not to be confused with the later gold-based exchange, BitGold) was described as an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published. A currency system based on a reusable proof of work was later created by Hal Finney who followed the work of Dai and Szabo.[citation needed]
