We would like to know what is the demand for such service - PayPal->BTC.
there is a lot of demand and you will have to deal with a lot of competition
https://www.bestchange.com/bitcoin-to-paypal-usd.htmlCould it be useful for you?
of course is something very useful, but for a new service and without many positive feedbacks it will be very difficult to have many customers in a short time. I suggest you create an ANN Thread here in the forum so that you can win the confidence of the people
