If you will participate in Telegram mini-airdrop as it’s known as tap to earn those are free airdrops you don’t need to spend money, although now some airdrop require to make a transaction, and in some airdrops if you will spend big then also rewards will be huge, i see it’s happen in Catizen. Every airdrops will not be pay that's true but some airdrops already paid big profits as like NOT, DOGS, and some of going to list on Binance in this month.
