Would you prefer to pay in Paypal or Bitcoin (no matter what kind of service it is)?
I would do Paypal, since it's more convenient for me in the end all things considered. But especially with what @o_e_l_e_o mentioned regarding maybe wanting to stay kind of anonymous, I could also see me going the
BTC route. Really hard to give an one fits all opinion, with the few information you provided
I think your service will have something to do with gambling/betting and if thats the case, then you should look into Skrill/Neteller/ecoPayz as well, Paypal is not that common with gambling.
As @suchmoon hinted, fiat is still the elephant in the room in general and it's the same with betting/gambling. Don't get fooled by the gambling section, where there seems to be a huge hype around gambling with crypto. Gambling is still a fiat business; but it's getting better
This survey in general is probably not very representative in a Bitcoin forum. If you have 50/50 here, you will have 10/90 in a non-crypto forum - or even less. Not offering any kind of fiat payment, will cost you a lot of potential customers imo.
