How can I profit from Bitcoin exchange arbitrage?

When you noticed a Bitcoin arbitrage opportunity between Bitfinex and Bitstamp, you could then immediately exploit it by buying BTC on the exchange with the lower BTC price (using the fiat you already have on that exchange) and selling that same amount of BTC on the exchange with the higher BTC price обмен биткоин на приват

In a highly simplified example of how cryptocurrency arbitrage works, you would search for a specific coin that's cheaper on Exchange A than on Exchange B. You then buy the coin on Exchange A, sell it for a higher price on Exchange B, and pocket the difference.
