Actually some traders don't follow the trading rules and regulations hence they face a huge amounts of losses instead of profits. I suggest themselves with trading platform, they should create demo account for trading because they have very low possible to losses.
they didnt set trading plan which is usefull controlling loss and profits forecast. dicipline with trading that arranged before will not make us suffer huge loss, every trade have strict stop loss and good ratio between risk and profits. trying our strategy on demo account unfortunately didnt provided at cryptocurrency exchanges, perhaps it could be important feature that will developt in near future.
