Starting a small amount on trading is better especially to those first time on trading because their is possible that your capital on trading got lose. Try to study the coin before you buy see if that coin have a good dev and have a good project before you buy.
I have started trading using a small amount with Binance, but I couldn't buy anything as it requires at least 0.002 BTC to trade. Are there any other sites which you could suggest that doesn't have a minimum limit to trade? Any suggestions will be appreciated.
