Increasingly it has become very difficult for online workers to make money legally without investing much money. Many of the better online money making opportunities are reserved for the well connected, especially relatives and friends of government employees, politicians.

Some older professionals from poorer communities do not wish to work offline due to the risk of fake cases by the ruthless rich and powerful. They find that all the better online money making opportunities like writing work are not available to them due to the lack of transparency in government agencies.
So working on the various crypto websites remains one of the few reliable online money making opportunities available. Though the work at the crypto websites is often low end and time consuming, some of the websites/apps are honest enough to pay as promised. 

After feeling frustrated at the brazen theft of online advertising revenues, the online investor making huge losses, has tried doing some crypto work, and the income from crypto work could become a significant part of overall revenues for workers and investors from poorer communities, who find it difficult to get paid work online otherwise.
