I’ve the worst one by a mile. In november I got into exchanges so I bought 5000 kucoin at 45 cent. I held for two weeks until I heard a rumour that COSS exchange was the better bet. I sold for at a profit 60 cent and bought into COSS at 1 Euro. A couple of days later Kucoin exploded . I bought and sold too early. It went to 16 Euro at one stage . That would of been the mortgage paid! COSS increased to 3 Euro but I still held and now it’s 5 cent a coin. What potentially was 70k is now around 600 quid. You win some you lose some.
