A trader must know when the right time to enter and exit, in contrast to inventors who only sell according to a specified target. Therefore, it is very reasonable for traders to use stop-losses to minimize the amount of losses, It is true that trading is not only ready to make a profit, but also ready to face losses. Most importantly, the amount of profit earned must be greater than the losses experienced. Good traders must be able to analyze the market well, so as not to be speculators. So if we can plan a strategy well, so that it is easy to become a successful trader, by collecting as much profit as possible.
This is exactly why being an investor is a lot easier. All I have to do is buy at the right time and wait, I can wait over a year if I want to, I do not have to check the prices every 5 minutes, I check them once a day and that is more than enough for me I do not need to recheck it because that is all that I need.
The bad part about being a long term investor is that you end up seeing huge moves while you do nothing, like I bought some under 10k and didn't sell any, I could have sold over 60k and bought back at 30k and could have owned 2x more bitcoins and that is the part where being a long term investor is a big challenge, you end up seeing big moves and some of us act on it and others just watch it.
Trader on the other hand could lose a ton of money during these moves, or could make a ton of money as well, it all depends on the talent, it requires more talent and knowledge than being an investor and it requires a lot more work.
