Quite right!, but this unfounded speculation on luftgeld or unreal estate is only half the badness.

The other bad half is crime. And no, I'm not talking about people stealing cryptocurrency from the nouveau riche, who cares?

Ransom attacks are the first things you think of, and they are actually bad, but they're tiny compared to money laundering.

Trillions of dollars a year vanish from the economies of the world through direct government graft, bribery and corruption, but also through tax evasion by the rich and the grey economy.

Some significant portion of this theft from the People, mostly by the Usual Suspects, by the rich and powerful, goes through cryptocurrencies.

If it weren't for the crime aspect of cryptocurrencies, it all would have come down years ago.
