Maybe you buy Altcoin at the wrong time and buy a coin that is not quite right. So you are currently disappointed with the decision you took the other day.
In buying Coins it is necessary first to research the coins to be purchased and to analyze the market first.
Actually, if you already have Bitcoin then sell it and buy Altcoin, I think it is a less right decision. Bitcoin is better than any other coin. Make this a lesson for tomorrow to be more careful and avoid mistakes ever made.
