Not only do I want to avoid exchanges but also banks, which is currently the most convenient way to withdraw money, but if I were to move funds to a bank account, they'd get taxed at 24%, which is a huge percentage. I've also thought about Bitcoin ATMs, but the majority of them here require some sort of KYC and feature expensive fees, although they may still be a better option than bank transfers. Is there an actual, reliable way to exchange bitcoin for cash in hand? My best guess would be a P2P transaction in person, but that's quite unlikely.
I guess you don't have any options but go to the old and traditional way - P2P. But the risk is there as well specially if you don't know the other party, so it's going to be very difficult to find one specially if we are talking about thousands or even millions of dollars involved in that kind of exchange.
Or probably just break it down, instead of looking for just one person to do transaction, then maybe 4-5 will do and make it like every other day.
Bitcoin ATM too will charge you a lot if you do transactions, so not just KYC but a chunk of money is going to be deduction in your end.
