Airdrops and bounty are still the best ways we can own free cryptocurrencies. In the past, there were a lot of very good airdrop projects for users, the application like the Hydro project in the past has airdrop for users of the amount of hydrogen that at one time it cost more than $ 4,000 - which is crazy. Is that right? However, there are also many airdrop projects that are scams and we don't get any reward. But, in general, airdrop projects are still worth doing, aren't you?
