It is actually a big gamble I am not ready to take. I can't pay before earning.No, not really. I don't trust any website that requires payment just for registration without even proving they are legit. I'm always skeptical about those kind of platforms because you don't even know the estimated amount you can earn and you can end up with a loss.
I can pay to acquire knowledge but to pay to sites before receiving any service from them Is definitely not possible.
