the title says it all, i wanted to learn some advice from you guys, how you guys actually manage trading if you already had with that such amounts or more
It is never worth to go all-in anywhere. I mean some traders sell only half of their coins when price is really high, because they don't know how price will change in future, price might rise 3 times next day, so they still keep some coins for that. Same with going all-in in one coin, it's too risky as you don't know how price will change. Maybe it will fall by 50% next day... too risky.
