my 1st day in trading is not that cool, i invested in the coin like a cheap one and then the coin keeps on selling high and i did sell my coin for me to gain profit but suddenly my sell order didnt hit, i dont know the reason why or maybe some buyer  dont want to buy more coins, so i wait a little longer and then i cancel it and sell again my coins at the same price i bought but i lose some sat due to interest of the market exchange.
