OP, you should move this thread to another section. Cloud mining topics should not be posted here. I think you should move it to the scam accusation or services. Please read the post of MODs here

Regards this bitminer.io. Surely this is a ponzi scheme. Just by looking at it and judging how much returns they are promising for sure this is a scam. It's really too good to be true. Another sign is that the affiliate program is so generous! How can a service give out 20%-100% as their affiliate program! So OP, if you did invest here. Say good bye to you investment. The company does not own miners nor do they really offer miners, it's all a scam!
Of course bitminter.io is a scam! They also seem to mine bitcoins at first for free, lol. They say that, ('supposedly'), it can mine bitcoins just by creating an account and clicking start! As if, and what an affiliate program they have. As known by most members of the community here, if its too good to be true, it probably is. The catch on bitminter.io is that the withdraw button doesnt actually work. Same with many other cloud mining. Some might pay out at first but after sometime, they just pack up with your investment, and close down. Then most probably, the same people open another cloud mining service, under a different name, and based on a different location, and repeat this stuff.
Nope, cloud mining is too risky, no one who has somewhat knowledge about bitcoin will invest there.
