Its very complicated to me as well. and i have had crypto for years, it just sits there! But El Salvador has made it a currency and you link it to like an online bank and get a debit card and pay like normal.. do i understand it no. When someone said in 2015 do you want to buy an online currency i say why not.. and that is how i started. I still know nothing! NFT's i do not even care to learn!
