I know this one, I've watched this fiverr after they sponsored one of Mr.Beast's youtube video. Upon searching to it, I found out that you can earn a lot from it using your service as a freelance.
You name your price in fiverr, I suggests you OP to visit this one.
You need unique skills to be approved in Fiver. If you can only provide writing etc, it would be really hard. On top of that, there are dozens of freelancers out there on that platform. Unless your skill and product is really good, getting $100 a day or $3k a month is nearly impossible. Crypto or not, it's not possible without a long and hard process.
