Here's some information about crypto currencies from our MLM expert in exile. Eye know you will find it interesting.
If MN members would like a plain explanation of how crypto-currency closed-market swindles (aka pyramid scams) function, invite them on my behalf, to take a look at this tragicomic UK civil court case from 2006.

In the case of 'Treasure Traders,' the crypto-currency had tangible specificity i.e. it comprised little bags of effectively-valueless gem-stone chips (bought for pennies) which the 'MLM' racketeers peddled for an outrageously-inflated controlled-price (thousands of pounds).
These latest crypto-currency 'MLM' rackets are virtually identical to 'Treasure Traders,' the only differences being you can't actually get your hands on the totally-valueless wampum which the 'MLM' racketeers are peddling for an outrageous price which they control.
In all cases, 'MLM' victims are deceived into regularly buying the effectively-unsaleable wampum at inflated controlled-prices, because they are led to believe that by doing so and recruiting others to do the same, they will eventually receive an unlimited reward. Almost anything (provided it is cheap, and/or easy, to procure) can be used as wampum to launder the unlawful losing-investment payments into closed-market swindles
