Especially in poloniex as the volume was enormous.
The volume was over 1 thousand bitcoin, and the trades were really dynamically.
Did you manage to margin trade or something? I haven't had much luck with Eth. I mine it so i'm okay and the profitability is still good but for flipping it, the scene was not very good for me. Maybe someone more experienced could do better, but with the price crashing at the moment, i just feel like dumping what i mine instead of holding like i did for a while.
No i don't use margin trading as i don't understand the fundamentals on how does it work.
I have tried many chances to understand but also people in the trollbox didn't recommended me.
Hah i see. Well i can tell you, its pretty simple, you need volume and spread, a significant difference in buy and sell price. You need a stable-ish value and you basically just buy and sell at the same time, within the margin between buy and sell. That way you might buy a 0.001 and sell at 0.0012 at the same time, getting you 20% profit minus trading fees.
Thats the concept anyways i don't have a recommendation on a coin or a indepth suggestion. I'd guess if you google it you could find someone nice.
