I set my failure or loss by waiting for the price to go down and after that buy it again at the right moment or the right moment because the price will definitely go back up, and preferably trading do not use all the money there, you put money to overcome this loss.
Putting the whole money in one investment is not a suitable idea. Before practically starting some investments, there must be an analysis of the market, the trust factor and much more credentials for the coin or source that you are going to invest into. Only then the decision should be taken with deep concern. Losses are not strange, just follow up them with good rehabilitative skill.
Yes you are right it is not good to get mad about something you are not familiar with, if you have more option try them all as bitcoin as many as investing, trading and gambling but the best one is investing as it is risk free and you will be confidence about your profit, but try to start with small if you find it well and good then go for more investment but keep it in mind that price use to increase and decrease never sell because of low price. Patience is the only thing that will give you profit at the time to crashes in price.
