You can buy azteco sats from orangelabel.co for as little as 4.5% fee. That's a simple and private way to stack without a draconian exchange.

If you're degen and want to fill send with credit card you can do that too but it's 9.5% fee (Azteco fee + cc processing trad rails are slow and expensive visa lives to drain you fuck them)

All I'm saying is to stack like the state hates you.
