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.
Verification Requirements – The vast majority of the Bitcoin trading platforms both in the US and the UK require some sort of ID verification in order to make deposits & withdrawals. Some exchanges will allow you to remain anonymous. Although verification, which can take up to a few days, might seem like a pain, it protects the exchange against all kinds of scams and money laundering.
Dash, which was formerly known as Darkcoin and Xcoin, is an open-source peer-to-peer cryptocurrency with the goal of being more user-friendly than other options. Dash created masternodes, which provide incentives to users to help secure the network and assist with user-friendly features, such as InstaSend - which significantly speeds up transaction-processing times.
The first decentralized cryptocurrency, bitcoin, was created in 2009 by pseudonymous developer Satoshi Nakamoto. It used SHA-256, a cryptographic hash function, as its proof-of-work scheme. In April 2011, Namecoin was created as an attempt at forming a decentralized DNS, which would make internet censorship very difficult. Soon after, in October 2011, Litecoin was released. It was the first successful cryptocurrency to use scrypt as its hash function instead of SHA-256. Another notable cryptocurrency, Peercoin was the first to use a proof-of-work/proof-of-stake hybrid.
