... BTC translations were fast enough you could easily buy on bittrex and sell on poloniex. but BTC is so slow.
BTC will always be seen slow against arbitrage trading because it takes 6 or more confirmations at both the exchanges to credit the BTC and make it available for trade. Though, the difference, like you think, is not even that much to curb with the fee that they normally charge over a buy/sell trade, so leave the idea of arbitraging at these two exchanges and find something else.
I think every exchange sites are put a single confirmation to confirming the funds already received by the exchange site. I don't ever see the exchange site which it puts 6 confirmation just for confirming a funding from their users.
10 minutes for every confirmation with $0.5 fees. But it will get a lot of the fees for every arbitrage trade. The volatility has made it impossible.
here, i not agree...
if you want to do spread trading, you need to have an huge capital.
And you divide all this capital between the Exchange where you want to do spread tradin.
if you are focused in spread trading between USD and BTC, monitoring 10 Exchange,
in all this 10 Exchange, you need to have, USD and BTC...
and when the spread opportunity appear, you put 2 orders at the same time, in 2 Exchange...
thats all.
