Good question. So many of these jobs all you to work pseudonymously but your legal identity is still shared with some members of the organization (like execs/HR/finance) for onboarding purposes. Some just pay out in cryptocurrency to a wallet address.
Many of the benefits of being paid in crypto are just benefits of crypto in general: decentralized, permissionless, censorship-free money.
Aside from that, there's an emerging trend that I think is both really cool and will end up being the default way most people are paid. That trend is "payment streaming". Products like Superfluid [1] let you stream cryptocurrency payments. Staff could be paid in realtime rather than waiting to receive a monthly paycheck. That will prove really compelling for prospective employees and I think that most organizations will eventually make the switch to streaming salaries. Some organizations even have public dashboards that show how much is being streamed in realtime and to whom. The transparency is super cool!
In the near future, we'll look back on the way we get paid today as unbelievably suboptimal and anachronistic.
