That offer can earn you negative trust here, easily. The problem is that yours is a brand new account and Paypal is a reversible payment method--it doesn't even matter if you used escrow, because the PP funds can be charged back up to 6 months afterward. I suggest you lock the thread and find another way of doing this deal. Maybe someone else here will have a good suggestion for you.
Also when i pay with credit card through paypal? Does paysafecard works?
I'm not an expert on PayPal, so I can't give you a good answer about this--maybe someone else can. You have to understand that scammers love PayPal because they have so much buyer protection and they allow chargebacks like I described, and I think buying crypto with it is against their policy anyway.
