No one was born a wise trader. That attribute of wisdom comes with years of learning and tweaking of skill set which must have experienced loss of trades before one got a handle on it. If one is scared of loss one won't have a grip on trading. It's a win or lose situation once it comes to business, trading inclusive. One good thing about cryptocurrency is that no loss is incurred until the crypto is sold. This is unlike forex trading where whether buy or sell one can make losses.
