I often participated in airdrops and never received coins that could be sold and made good profits. I think this type of earnings is not suitable in order to receive money for investment thanks to it. It is much better to find a job in an offline business and allocate part of the money to invest in cryptocurrencies.
Last year maybe worth joining airdrop and use our reward for investing with bitcoin and altcoin, now hard get money from airdrop and invest with bitcoin because many airdrop become shit coin without have exchange market. my source investment from airdrop too but last year many worth airdrop for joining and I can use half for investing with bitcoin and altcoin.
