What’s an ICO?
Initial coin offering (ICO) is a controversial means of crowdfunding via use of cryptocurrency, which can be a source of capital for startup companies. In an ICO, a percentage of the newly issued cryptocurrency is sold to investors in exchange for legal tender or other cryptocurrencies such as Bitcoin or Ethereum.
Early token sales were held by Mastercoin in July 2013 and Ethereum and Karmacoin in 2014, but “mainstream” ICOs began with messaging app developer Kik in September 2017. By November 2017 there were around 50 offerings a month.
What’s an ICO Bounty Program?
Some crypto currency start up companies will give out free coins in exchange for simple tasks such as sharing their upcoming or ongoing ICO.
What’s an Bitcoin faucet?
Bitcoin faucets are a reward system, in the form of a website or app, that dispenses rewards in the form of a satoshi, which is a hundredth of a millionth BTC, for visitors to claim in exchange for completing a captcha or task as described by the website. There are also faucets that dispense alternative cryptocurrencies.
