Good that u learned from ur first mistake, all the best

I'm not saying that any coin is good or bad, but before buying, do we study the history of the coins that have entered the market and have been withdrawn? When they first came into the market, they were presented in good condition, but after they had been in the market for 3-5 years, the coin began to have a tendency to die. Is there anyone who thinks like me? Please tell me 🙏
