Off-platform payment
The AliExpress listing was only the introduction
Marketplace chat is converted to WhatsApp so there is no AliExpress refund path. Then the only “invoice” is a Bitcoin address. That is the point.
If a miner or GPU seller on AliExpress, Facebook, or Instagram insists on WhatsApp plus BTC/USDT, treat it as this case until proven otherwise with a verifiable U.S. merchant account and a carrier you can query without the seller’s website.
