One option would be to stack via stablecoins, you could swap cash for stables on P2P exchanges or give someone cash that you know and get them to send you a bunch of stables and then go trade that P2P or use an instant swapping service

Azteco vouchers are also an option, they come at a big premium and you have to buy in increments, the system we have here in South Africa (1 voucher) I can buy $150 at a time

I guess if you're looking to load up on a bunch of non-kyc sats your other option would be to start mining
