What type of products do you sell?
keep in mind people think they are selling "high risk" but reality is they are selling black market/borderline illegal goods.
Or, they are selling legal goods like Kratom, which violate the Visa/MC TOS and therefore cannout use credit/debit cards.
In these cases its best to use an alternative payment system which can inlcude bank transfers, echecks, btc (no one really will use it though lets be honest unless youre selling illegal goods), and also credit card workarounds.
If youre selling these kinds of goods you can convert and a lot of customers to use these systems bc they︀ know the goods are hard to come bye.
Juggling cashapps, skrills, or even setting up︁ your own payment page can be done for example becoming a BTC seller and than︂ accepting BTC as payment. Of course in that case you apply for a crypto selling︃ merchant account.
