From my point of view the problem is that most cryptocurrencies are used as speculation instruments, and there's a significant hoop to pay someone in crypto.
Building on top of Monero would alleviate some of those issues, while targeting an even smaller niche of people.
From a business perspective the landing page does not do any work in reassuring me. Focusing on fees rather than vetted freelancers, testimonials, and without any form of results "assurance", escrow system or dispute resolution why would any company take on the risk of hiring a freelancer this way while also gambling with all the issues crypto brings?
