If the prices of virtual currencies on multiple platforms are different, can you buy low and sell high to make a profit?

Aug 2021
A friend of mine told me that due to inflation in Nigeria, many people choose to buy cryptocurrency, so the price will be higher than other countries. He bought Bitcoin from Binance and sold it on the Nigerian exchange. He made a total of $60,000 in 7 days.

He bought Bitcoin at Binance for $45,000 and sold it at a Nigerian exchange for $53,000. One Bitcoin can earn $8,000. After deducting withdrawal fees and transaction fees, you can still earn $7,500. It only takes 30 minutes for one operation. Do you think it is feasible?
