Some remarks on this.

1. Almost all internet users were using it for legitimate purposes.
2. The overwhelming majority of (~80%, although easily provable/traceable minimum is ~40%) crypto users are using it for illegitimate purposes.
3. Apart from purely speculative/non-legal purpose coins, to date there is no viable use-case for D-DLTs. Given token economics and the hundreds of D-DLT platforms and more every day, there will possibly never be a lasting viable use-case.
