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.
