Payment from Airdrop is not guaranteed. And a lot of time has to be spent here. So if someone has such time then he can earn from Airdrop. By airdrop legit I look at those airdrop projects that bring a new concept and don't copy the structure or strategy of a previously running airdrop. And I've seen most of those projects do good. So you can use my strategy if you want but I won't guarantee you payment for them. Payment will depend on your luck and your own strategy and time spent
We know that the payment might not be guaranteed but I will still suggest that you do all the once you can so that when people are making money you don't miss out from it and that is one of the most interesting even if you don't make money from a particular one you will know that you have tried you best in playing all the airdrop games, missing out, because this period I have see that majority of this project are that are running this airdrop are always listening so the chances of it failing is very hard because they will try to get the publicity that they want and you will even see people that are ready to buy the coin when it is eventually released to the public after the presale and some people are even ever ready to buy and even bitcoin have a target already if how they want to engineer a way either by holding selling and then trading depends on how everyone wants it to be.
New trends keep happening in crypto and it is actually something that you will be able to invest in, they will make it more interesting, that even aside the money you will get the fun to is their and their is prosperity when it comes to crypto is now for you to do what is best, and we keep learning new things everyday, the energy will determine the momentum and the result to.
