Crowdsale is a term commonly used in the cryptocurrency world. Crowdsales are similar to ICOs (Initial Coin Offerings), but they can be much more than just an offering of coins or tokens. A crowdsale can be used to raise money, create awareness for a new product or service, distribute tokens or coins, and much more. Crowdsales may also be referred to as token sales, token presales, pre-ICO sales, pre-ICOs, ICO's with no tokens issued yet (sometimes called "Dutch Sales"), etc.
Crowdsale articles describe the mechanics and technical details of token sales. These may include a sale's history, target market, and use case. Crowdsale related topics also include security and investment reporting and trading platforms for blockchain tokens and cryptocurrencies.
