Really good review brother. Do I think Bitconnect is a HYIP ponzi? Absolutely. Can I prove it? No.
These programs always work fine until the day they don't. When will that be? I have no idea, but your projection seems reasonable. I imagine quite a few people will continue to pour money into this thing. Some people never learn there's no such thing as easy money.
you remind me about fiat currency!
There are definitely some ponzi type schemes in the world of crypto. I have an aquaintance that got sucked into a mining ponzi scheme. All of the ponzi scheme markers were present, like paying large amounts just to be a part and then they try to get you to recruit other investors.
