Perhaps I will say the obvious things, but the main enemies of the trader are fear and greed. For these reasons, it is sometimes difficult to achieve success in trade. So do not be afraid and do not be greedy))
Greed is main problem for me now. I mean when a coin get pumped, i usually wait for a bit higher but then it is not like from what i expected. That is why actually i confused it is my greed or i wrong to put sell order.
