About my experience: the main difficulty is not to find an online (quite) well-paid job (during 11 years I found several online jobs and some of them offered a discreet salary), but to find a long-lasting well-paid job. For ex.: 10 years ago I was a Trivago writer and I earned well until Trivago definitively close the writer's activity. Then I found another content marketplace, but last year it went scram. So I stopped with this latter too. Another point is a content marketplace requires us to work several hours per day (not compulsory, but necessary to earn at least a part-time salary). Compared to offline jobs, online jobs require us to work double or triple time in order to earn discreetly. And we must be careful about what we choose: if we live in a tier3 or tier4 country, we must know the majority of survey panel are a big waste of time for us. Telephone apps that claim are pay to apps: more or less 80% of them go scam (but I found reliable those which pay cryptocurrencies, cashback apps and PTR apps about the news. Unless we don't have very high and uncommon skills, paid to post forums are into the best for us living in tier3 and tier4 countries: if we have enough time to dedicate to several of them, our earnings become interesting. And if we know at least a foreign language, at least intermediate level, we can participate in foreign forums too (PTWs forums are worldwide open), increasing earnings. My currently best pay to are both Italian and English speaking forums, but publishing platforms, cryptocurrencies earnings, too. My current best platform is publish0x. I signed up to red.cash too, to have one more platform when I'll have the free time I'm now missing due to a postgraduate course. To work online, we also need to adapt to changes, because unfortunately, it happens a legit site close its activity after a while (a point is the majority of the owners are not millionaires and may face financial issues as time passes by). Or scrams. I often saw this happening during coronavirus. We are in need of constant research to add new paid to sites.
