Re: Currency is not the same price, you can buy low and sell high profit?
Recently, the price of Bitcoin has fluctuated sharply, and arbitrage windows have appeared on many exchanges. The price of Bitcoin on Binance is US$47,000, while on some exchanges in South Korea, the price of Bitcoin is US$51,000. If you buy in Binance and then sell in South Korea, you can make a profit of $4,000. I am considering doing this. I want to hear your opinion. 
We are already in 2021, it might be a good idea to do arbitrage in 2017, but now you have to compete with bots. So the chances for a average and regular traders are very slim to make profits thru arbitrage. And then you also have to factor that withdrawal fees and KYC procedure you have to undergo. So just be careful as the risk is also very high. It's sounds easy in paper, but it's a hard trading strategy to execute, in my opinion.
