Why not a crime ponzi and HYIP company in bitcoin ?
maybe managing catch?
The problem with this type of "investment" is that almost every time operator runs away with all money and stole from everyone who invested in.
My thought are: if you don't know whether it is a ponzi or not because operator disguised it as some standard investment it is definitely a crime.
But if you knew exactly that this is ponzi and operator stated that plainly, then it is ok to run these type of activities. Some people would like to gamble and earn big money this way.
They know if they are late they are losing everything and if they pull out in time they will earn.
All in all. It is a grey area and I would never recommend investing in known ponzi because it is too risky.
I tried and invest my money many times in HYIP programs and lost money almost every time.
From my experience, every HYIP is ponzi and crime but people are so desperate to earn some money on Internet, that even they know HYIP is ponzi and crime, they will invest anyway, with desperate hope to get some money back.
I don't think that anybody seriously think that HYIP is legit business butr people will try anyway, it's some type of gambling or casino.
I guess, it's human nature, to expect to get something from no effort or work involved.
