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
I will never do that. I will never put all my money into single coin even the founder comes to me and says it's going to be success ICO or altcoin in the near future.
Because I have considered or more or less learnt none thing, "crypto world is probability game" and you never know what is the chance of winning or loosing it. It's very uncertain about coins and should not believe in one coin only. Must go with different coin and this is the way we can decrease our risk.
Haha! Dont worry; no founder is going to beg you for this purpose. Good projects easily gain attentions and grab investors. But as far as putting all funds in one coin is considered, I myself will not suggest investing all funds into one coin since diversity always proves good in making big profits.
