Or they say: you loose money because you must buy back at higher price.
Not true, if i buy back more expensive I just have less profit but no losses. It happens me sometimes, but I sold then as I am expecting some lower prices because price hits a sellwall and expecting to buy back cheaper then sellprice. Once sellwall is pulled away suddenly, I have to buy more expensive than I sold, but it is not the problem for me. Every trade is a new one.
Yeah, cause the at the end of the day, a profit is a profit. Even if you have to re-buy a bit higher, you already made initial profit based on your earlier expectation.
That's the difference between trader and coin holder. Trader will set a realistic target and stick with that. Holder will set unrealistic 'to the moon' target and start panicking when their target is not reached.
