Check out the website https://crypto.jobs/ there are tons of work there with `remote` option available. I mean there are thousands of views on each of them given enough time and that means you have one in a thousands chance to get that job but at least you can see that people are still hiring.

For every business that starts to hire people for bitcoin there are hundreds of people who are looking for work, so freelance didn't die, there is just more competition now. There is actually more work to be done via online working (aka freelance or remote work) but at the same time there are more people who would like to make money that way, hence even when there is more work to do there is also less work to do since it is harder to get hired and get paid as well.
