What is an airdrop?

Where can I sell my tokens / coins?
Usually airdrops take place while the project is in the ICO (Initial Coin Offering) phase or even before that. This means, most coins are not yet tradable on big exchanges. You can either wait until it goes online or look at smaller exchanges that sometimes already trade them.
Where will I receive the tokens?
Most airdrops require you to have an ERC20 compatible wallet. We recommend you set up a wallet for free at www.myetherwallet.com
Some airdrops do not work on the ethereum blockchain, instead they use NEO. To set up a NEO wallet we recommend you to use https://neowallet.cn/
Alternatively you can use any other ERC20 compatible wallet, as well as any NEO wallet.
In the airdrop you will be asked to provide your wallet's address. Once the airdrop is concluded the project will release the tokens and send them to your wallet.
