This doesn't make any sense to me.  The easiest way to describe arbitrage is that it's trading to exploit price differences for profit.

Arbitrage between crypto exchanges is very risky even with a bot.  While the differences might make arbitrage appear appealing, there are often significant transaction fees, trading fees and shady exchanges which make it a tough business to get into, especially in the short term.

If you're trying to do it on your own without a bot, I would suggest going for obscure exchanges and low-cap coins to try and find price differences which people haven't thought about very much.

Be careful though.
