i have little dout in transaction fees of paypal and bitcoin.so if you hade made transaction in both then tell me your idea on it.
paypal have more and higher transaction fee,everybody knew it,some people post the proof on this forum. and i'm sure,if paypal user know about bitcoin,they will consider to replace their payment method.
paypal users already know about bitcoin. but they still use paypal. because they think the paypal is more reliable than bitcoin, there are many reasons for that. cost fee charges will not make users turn of paypal
