If you want to make profit you do not need to be greedy. 20-50 percent for each coin is an amazing profit on a falling market. Do not make this mistake to await 1000 percent profit for each single coin or you will be left with nothing.
the starting profit of mine was in a few years before was very much good but when the market was falling down it reduced to half of its so this is the situation that happening here but we don't blame any other for this changes it always happens when Crypto gets going to deeper.
