now it is a lot of airdrop but the price is not good, because maybe too much airdrop so the price of airdrop coin is very cheap, but we just follow the existing airdrop maybe the price will rise in the future. it's in my opinion.
So you are implying that participating in giveaways and letting the coins lie is a good strategy. I guess it may actually work out, but the chance of an airdrop coin suddenly growing in price is quite low, so it's still a gamble. At least, you only lose your time instead of your money.
