What is a cryptocurrency airdrop?
In the crypto world, an airdrop stands for free crypto tokens. These tokens, which you can earn, are mainly from new crypto projects. Airdrops normally take place 1-3 months prior the ICO of a project. The reason for this is, that new projects want to increase their user base and want to have a virtual domino effect. In addition, they also want to attract new potential investors for their project. Many people say the year 2018 will be the year of cryptocurrency airdrops.
There are also airdrops for established cryptocurrencies, but they are less frequent. Holder airdrops are more common - if you hold a specific cryptocurrency at a defined time (called snapshot), you'll get a part of the new created cryptocurrency, based on the amount you were holding and the defined ratio.
