So, sort of mining games? I believe they still exist. The clicking or whatever but if it comes to payment, you have to pay something you find out later.
You never earn dear, at the start it is to make you play and preferably pay as well. Only if you ear a bit you are motivated to continue and talk others into it.

Keep this in mind: if it sounds too good to be true it is not true and if it would work everyone would do it and poverty wouldn't exist.
