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 have learned a lot from your case dude, try to go out from the market when you have been getting a lot of profit from your campaign. it says that if the team or project have a lot of uncertainties and you should never try to keep the coins for the long term. So many hunters have been learning from here and they were selling their reward when they were seeing their reward worth some bucks.
So many people have ever experienced the same thing like you.
