arbitrage is quite an interesting topic, but here we must also find such a coin and buy it out at a low price and sell it on another stock exchange at a higher price. I found a couple of such coins in the summer where prices on exchanges differed by 10-30%. usually such coins on small exchanges with small volumes. But then with $ 300 per week made $ 2000. after the prices became equal and I did not find similar coins matching all the criteria, but it was worth it
