For me, the Bitcointalk Platform is ranked number one among the 10 platforms that you have described one by one above. On the Bitcointalk platform you can earn BTC fractions by following the signature campaign, you can also earn money by selling services here. Many users use the Bitcointalk forum service to increase their wealth by selling goods and services.
Everyone who has experienced how easy it is to make money on the Bitcointalk platform will always take the time to visit the forum. Here there is also a high level of trust, every transaction that occurs will always benefit both parties. I have never used another platform, Bitcointalk is the only platform I have used so far and have benefited a lot in terms of money and knowledge while I was here.
I agree, I have seen this list before and worked with some of them before, around maybe 10 years ago or so, and maybe it could be a good side income for someone who has a poor nation, but that is it. I mean this isn't even side income for an American, it is not a side income for a British or a German, it could be a side income for someone who lives in a very poor nation like Argentina or Venezuela.
And top of it off, that is not even main income neither, I am saying side income, so no matter how poor your nation is, you can't just live with these, that's not good enough. However, if you are a lgendary member and willing to write 25+ posts a week, then I am sure that you are going to do fine with bitcointalk income, there are places that pay 100+ dollars a week, that's 5200 dollars a year, meaning on average it is 433 dollars a month. Thinking that there are plenty of nations with less minimum wage, you could live with bitcointalk income without a doubt.
