There are many who believe that Bitcoin was created by the Bank for International Settlements ( https://www.bis.org/), as an experimental project to test a future world currency.  The limits placed in Bitcoin prevent it from ever becoming the dominant world payment system, and the banker controlled development can benefit from the knowledge gained from thre eperiment.

Cryptocurrencies have no intrinsic worth and are useless as a form of exchange. They entail exorbitant transaction costs. They are very slow. Together they have turned into an ecological nightmare.

They are not backed by the assets and revenues stream of an established state. Most can be rendered worthless by fraud or digital manipulation. They are essentially ponzi schemes that masquerade as citizen currencies beyond government control.

Such are the broad findings of the Bank for International Settlements, the Swiss-based ‘bank of central bankers’ and the leading global authority on the crypto-craze.
