This article is largely correct. You can argue that it's "not technically a Ponzi," but rather some other type of scam, but the semantics are not interesting.

The following excerpt is a point that many seem to miss.

> In fact, investors won’t — on average — be able to cash out for even as much as they put in. Much of that money went to cryptocurrency mining. Recent analysis shows that around $25 billion and growing has already gone to Bitcoin miners, who, by best estimates, are now spending $1 billion just on electricity every month, possibly more.

> That money is gone forever, having been converted to carbon and released into the atmosphere — making cryptocurrencies even worse than traditional Ponzi schemes. Most of the money lost in Bernie Madoff’s infamous Ponzi was eventually clawed back and returned to investors. Much of the money put into cryptocurrency, even if courts could trace back tangled webs of semi-anonymous cryptocurrency transactions, can never be recuperated.
