It's simple if you are a freelance website centered in Bitcoin/Crypto only payments you would only have freelancers who are interested to get paid in crypto posting for job offers in your website, you won't be having problems on people joining who are wanting to get paid via Paypal or Bank transfers. Your only problem is there is already a lot of freelance websites existing that are accepting crypto payments such as
coinality and
xbtfreelancer which are already popular in the freelance community, you would have a hard time getting people interested joining in your website especially if you are using Facebook/Google account log-ins in order to sign up in your website. It's sort of a privacy issue for them as they don't want their social media accounts tied to some website especially if they are new and not yet reputable.
Thanks for the response Theb!
I guess the concept is to combine the utility of Crypto with the globalised nature of fiat. We also use fiat in the background to make cross border transactions seamless and to decentralise the dispute process. Things that aren't usually done at the moment in the mainstream.
Xbtfreelancer seems to have a large community but they seem to only have 5 jobs active at the moment. They also have the concept of bidding which I'm not fond of because it quickly reduces prices which often come with reductions in quality. Coinality has posted like 2 jobs in 2 years too + it points you to a variety of websites as opposed to functioning as the facilitating platform (unless I've misunderstood).
The issue of privacy is a very interesting one, but people don't have to log in via their socials, they can login via a normal email login. The Google & FB makes it fast and smooth but I get you
