Well I found a couple of coins with a substantial difference (+10%) in price on poloniex and cryptsy.
So I was thinking to have a go at buying, transferring, selling, buying something else transferring selling and start from step 1.
You are right but the transfer between exchanges is not instant so you have a chance to lose at least the fees if you trade at the same rate if you get any delay when transferring the coins from exchange to another, sometimes yobit has good rates but it lasts short.So I was thinking to have a go at buying, transferring, selling, buying something else transferring selling and start from step 1.
I've been looking at it for over an hour now and looks like pretty stable even the 24h low and highs would still be profitable.
Might give it a go. It will give me some experience with the different exchanges, up to now I've only been on cex.io and that one seems pretty quiet.
