Is through moonpay. So moonpay took my credit card and I bought usdt. Then it showed up in my bitmart under assets usdt then I bought safemoon with usdt.

I also bought bnb on binance.us through my debit card. Once those funds cleared(5days) then I transferred it to bnb bitmart. Then I had to trade bnb for usdt then buy safemoon with it.

I am currently waiting for my hold to expire on another round of bnb through binance. Not sure what I am gonna buy. Was thinking huge or moonstruck but did I miss the boat on them?
