you can earn starting from nothing and not know anything, but you need time
if you do not have the capital, you will not collect anything even if you were patient for a long time.
I didn't say that you will not collect anything if you do not have the skill, but the profit will not be sustainable.
You can actually collect airdrops for money when starting out, even though more than 90% of the airdrops are crap. But still, it's possible. Luck takes a huge part of this, as you're going to need to receive the good airdrops for it to be worth it. Though it could take months or years for the good ones to flourish.
