Many people regret that they did not buy BTC while they first knew about it. For some, they did not sell BTC while they could.

For me, I got MWC & HEX for free from airdrop to BTC HODLers, but dumped them before they peak. I could easily make 10x of my existing BTC, if I held them strong.
What is your Biggest Crypto Regret?I want to believe that, if everyone in the crypto space is asked about one regret or the other, definitely there would be one or two of such. A friend once told me, you can't get things right always in the space.
Part of my regrets was when I sold some airdrops for just $15 and just a week later, the same amount of coin worth about $400. Just a little patience from me, but I was too in a rush. A little patience at times, can lead to a huge positive transformation.
