each user can safely buy bitcoin and pay on the website, this is available for each country
if u use paypal from seller, u need understand this:
1. When a user pays to the seller, the seller withdraws Paypal money to Bitcoin with % to pay to the coder. Because the coder only accepts in BTC. To make a PP >> BTC exchange we pay from 20 to 25%
2. Also, we, as sellers, should receive our %. This is our work and bread.
