now there are a lot of airdrop, i want to go crazy because of them, too many scams, many people will not know what is the real project
What kind of craziness you are thinking about them? you are crazy of beating them because you've been a victim of dozens of these scam airdrops?
Knowing the real project is quite hard if you just keep on joining random airdrops and this is why many are crying at the end if the airdrop they joined became scam.
You can use different strategies to pass airdrop, but it is best to perform everything, well if you have free time . If time is limited, of course you need to weed out the excess .
