i'll check some of that but i doubt that you gonna earn the much money at this month or the next one or the previous 6-7 ones :P

First of all doing all that do you and i don't speak generic, do you earn 1000 or more per month?

Moreover a lot of airdrops need different wallets, so one must have so many wallets and then if we wanna transfer them to coinbase witch you suggest he/she will need to change and change the coins paying and paying fees so the final value will drop a bit.

I may sounded harsh but that's the reality. Some of which you mentioned i had no clue about their existence though, so thanks for mentioning all these sources and i am gonna check every single one of them!
