If you have your own capital, then why don't you just arbitrage yourself? registering on a global exchange is not difficult, why do you need other people's help?
That's a good question!!
Of course, I also tried to buy cryptocurrency from overseas websites (Coinbase, etc.). It is convenient for me to do it myself too.
However, it was said that Korean residents could not make purchases.

That's why I found some friends to do crypto arbitrage with.
If you can't make a purchase, why don't you withdraw from the Korean exchange to Coinbase? Then exchange it for whatever coins you want on Coinbase, of course this can be done.
