Every trader will always look for profits, it depends upon the situation of the market. Of course, there are chances to lose money in trading, but we should trade them in a planned way because without analysis and techniques it is impossible for us to make profits.
Yes, we cant prevent losing, whether it is for gambling or trading both we can experience losing, especially when you long term hold a coin, it will not give us the assurance that when we will try to trade a coin, there is no possibility that we can get a high profit in a long term, some of our coin becomes shitcoin now especially those coin wayback 2017, they are now shitcoin and we lose money, me I think lose about 1btc last 2years ago, and it is sad.
