It has something to do with ignorance I used to be like that I thought back then that HYIPs are legit and they are backed by legit companies that are licensed because we have online banking and being ignorant makes us think they are the same until you got scam that's where you do research, they say experience is the best teacher but online you can skip that if you know how to research and use your common sense before investing.
These scammers know that noobs online are endless there will always be new victims coming in or getting into their trap.
I remember a lot of HYIPs were registered in the UK. They alway claimed they were doing forex trading and offered ridiculous returns like 9000%.
HYIPs, doublers, and cloud mining investments are all very similar in nature. They're either traditional ponzis that pay a few early investors or just outright scams that take your money and don't pay anybody.
bitdouble.net is one more doubler scam site that's out there. This one's different because it's got a dedicated affiliate deal and it's saying it's certified. Their faq's says the minimum you're allowed to deposit goes from 0.003 BTC and the maximum is 0.5 BTC. The confusion they're causing with professional appearing scam sites helps bewilder ppl.
Inexperienced investors should be aware that even if their registration certificate is valid it isn't enough to give an investment program legitimacy. This website's registration number corresponds to a different company on the Companies House database but it's very easy to register a company in the UK and many scam websites are actual legally registered companies.
