The worst is that when you know everything but you did the same mistake . As everyone knows very well that what the neo coin is in actual ( better by technology , better by the amount of the investors , better by the buying support also ) .
Here it seems that you are at the newbie level to trade cryptourrency .
Here I myself once made a big mistake during trade of bitcoin gold , I bought at 0.02btc and after that price get down to 0.014btc at that time I get into panic and that panic made me to sell the coin at 0.014btc rate with bulk loss , but after one week of sell the price comes back to 0.023btc that was really sad moment for me .
So here my suggestion for you to first learn basic and be definite that you will never sell your coins at loss at any condition that is a first and main formula to make profit in cryptourrency trading .
