Trading is not for everyone mate. In trading, profits and losses are both a part of it. It depends on your ability to make it work out. Always remember that your loss is someone else's profit and their loss is your profit. Given the fact that the crypto market is quite uncertain, we can never predict the future 100% accurately and thus, we may lose it all.
The market is a zero sum game and money flows inside it from losers to winners. There is no market in which you find only losers or only winners. There must be winners and losers exist together in a same market to make it an actual market.
If you make mistake, someone else wins and gets profit. If you make profit, you have to know that profit comes from someone else loses their money.
It's true that trading is very risky and people have to pay a lot of cost, money to learn from trading. The painful fact is even they trade a lot, spend a lot of time and money in loss, they might not become successful traders. There is more easily way than trading, it's investing. Invest in Bitcoin will help investors to get profit if they do it a long time like few years. If failed traders can change to be long term investors and choose Bitcoin for investment, they will become successful ones.
