Thanks - in principle I knew - but I'd like to have a really rigid statment from others as well:
If big banks, corps and all those PWCs, Deloittes, R3s,.... would just do tiny risk Analysis (and I fear that's where they're strong) of that above, would they invest in PoS ( they do not control) ?
Conjecture: banks are only interested in blockchains to replace their internal, expensive, legacy settlement systems. They have no interest in anything public or risky - they want total control.
Not quite. Banks would like to see e.g. all their OTCs build into smart contracts....
Further: Would you trust some Slockit-Hotel ? Some self-employed car ... ?
