My regret in crypto investing is that I didn't sell all the altcoins I got from the bounty campaign, now almost all of them have no price and only a few are still holding out. And I didn't buy much bitcoins in March 2020 when the price dropped 40% in a day.
You should sell your bounty coins, if you are in doubt, you can sell 50% of the total bounty reward you get, so when the price goes down at least you have taken a profit, and when the price goes up at least you still have your coins.
I still remember that when I got NEO from the bounty prize, I sold it for 2 usd, but not long after a few months the price of NEO went up above 100 usd.
