I have a slightly similar experience although mine isn't with trading, I have been doing airdrops and bounties from the beginning and I always hodl the coins with good potential and sell the bad ones, I once bought held a coin that j felt was good and I lost over $500 from holding it, now it is almost too worthless to look at but recently, that same coin started doing wonders and not only have I recovered all my loses, I have even made good profit, patience is a virtue in this crypto space.
