I never bought shitcoins. I got some as shitcoins through gift or a competition which I won and I did hold them for two years because they were profitable to hold. After two years when they became very less profitable I sold them and bought Bitcoin with that money. When I recieved them, they were around $500 but when I sold them, they were around $3k. The price of Bitcoin at that time was around 25k so all in all it was a lucky profitable gift.
