Airdrops aren't the best way to make money. Usually rewards you can get this way are so small, so airdrops are more like wasting time.
True, but there are also Airdrops that can give decent results and usually they are born from the top exchanges, because Airdrops supported by the top exchanges can be very promising and profitable, so it won't seem like a waste of time, but that kind of Airdrop very few and most of them are just scams.
