If i were you i'd refrain from using PA however i'd advice you to use a verified middleman on osbot like @Muffins or @Night. be aware that accounts can always be recovered so it's highly recommended to only buy from a trusted user.
you can sign up on binance from there you can deposit with crypto like eth / btc / ltc etc. and from there u can buy things like TRX XRP etc etc.. if u want i can send u a referral link to binance so that i get a piece of the cake aswel
