2. little coins that earned through airdops in 2017 they are not even close to 1$ and in January 2022 two of them did wonders, name is Avinoc and whackd token, I made 80$ from avinoc and 500$ from whackd, my main point here is if those coins have huge value at the time I would have sold them right? I took my eye off them because they have too low value...
The same thing happens to me...we usually didn't check airdrop coins for we think that they are useless and have no market value. I have that experience when a friend of mine tell me to check my wallet during the bullish season as many airdrop coins have been shooting up, there I've found some of my coins have a huge value. If it happens that nobody ever tells that, I surely miss the chance to sell them.
Then I think that we can't really underestimate them, that to proves that they are also unpredictable like others.
