Of course there are alternative of megatypers but the problem is that non will pay you decent amount of money. Unless you refer a lot of friends to those platform and you will be earning percentage of whatever they earn. The worse is that those reffered won't last as they will get tired doing such.
Though I have a guy that have made close to $1000 from website that pays to watch ads but that was because it got active refferals.
Well if you are still interested you can go to website called freebitco .in. it pays in Bitcoin, you earn 5 Satoshi per captcha which is really small. But it is better because it also have other things you can do to make money.
