The same currency pair on two exchanges with different prices presents a
basic opportunity for profitable arbitrage trades:
1. A simple example
on the Bitcoin: on November 13, 2018, 10:31 a.m. Paris time, the Bitcoin
was quoted €5600.9700 on Bitstamp exchange and €5785.9000 on Exmo
--> By buying and selling simultaneously on these two
exchanges, the gross gain (excluding trading costs) was 3.3%.
second example taken a few minutes later, on Etherum (second crypto in
terms of valuation) $204.94000 on Kraken and $212.13000 on Exmo.
That is 3.51% of immediate gross gain.
3. Last example few minutes
later, on Dash: $160.0800 on Cex and $163.8400 on Bitfinex.
is 2.35% of immediate gross gain.
And even after deducting significant
costs, the net profit remains attractive.
