Being a good trader has nothing to do with how long they have been on this forum or how long they have held Bitcoin in their wallet. Because being a good trader is based on his experience in the market and how good his trading performance is on the account he has.
If you ask me, have I become a good trader, I can't answer that I am a good trader because it is quite difficult to achieve that, but I am also not a bad trader, because the few times I trade I can get a profit from it, It's just that I don't really focus on it so I just do it as a side thing, but I understand about trading.
