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.
When you are trading with your hard earned money, you will not take such chances, trading must not be complicated if you stick to the basics, buy low and sell high and if you follow those basics, you will never end up in a loss how raw you are when it comes to trading, just use your common sense and have a better understanding of the market situation if you invest money in it.
