>> Shouldn't the fact that central bankers want to ban crypto make you think that maybe there's something here more than ponzis and scams?

Note that I do not support Gov banning crypto.

I see two things: 1. That there's a legitimate threat to their power and existence which they would do anything to mitigate.

2. Also, it could be that majority of their population are being exposed to unhealthy risk.

Take the case of Nigeria for example. MMM a ponzi scheme rocked the country in early 2017. People lost a total estimate of about 18 billion Naira (or $60m as of March 2017)

The Government actually warned people, but the Government has gained reputation for stifling any form of growth. Therefore, no one listened.

Or it's so bad everyone agrees.
