thanks for all that Info
is there a platform that works like poloniex?
I really like bitcoin trading, i just depsit and trade, i assume when trading shares it isnt that easy and i think the fees are higher than the 0.15% on polo
but can i do trades like on polo, on exchanges, saying I buy and sell within 30 min??
I talked to a dude in the bank and he said buying shares with less than 5 grand and without keeping them for a while is not really profitable
of course you can, and this is how i do it to get profit

but first you need to make deposit in btc or altcoins to make your first trade.
