This may work in theory, but there are some practical hurdles. For example, you need an account on both exchanges, perhaps the corresponding coin has to be bought first because you don't have any of them, withdrawals and deposits have to be possible on both exchanges, plus the corresponding volume. These were just a few spontaneous thoughts, and as far as I know there are already bots that do this. But ok, if you happen to see a profitable price difference, you could give it a try.

For me, however, it is less suitable, as time seems to be an important factor in arbitrage and I prefer to move slowly :-)
