I use cash app to send bitcoin it’s pretty easy. Once you place an order and get your total amount source will send you an address or code to send it to. Buy bitcoin for your total amount then “send bitcoin” and copy their address they gave you then send. Idk if those steps are exactly in order lol but there’s you a rough draft. If you have more questions a lot of times the sources will help you out with directions. Yeah that’s the website, as far as scammers go they’ll email your proton email posing as one of the sources, if you’re ordering via website for k4l you’re good. Some sources don’t have websites and you have to email them, that’s why you don’t want your proton email same as your sst user name. Scammers just be on here lurking then type in your username as an email in proton and if it works they’ll email you trying to “sell” shit. Yeah I’ll holler back on this thread in a couple weeks and let you know how it’s going
