The horse has bolted @richard78624 blockchain is here to stay IMHO, no person will carry gold and silver into a store, it is hidden treasure you hoard in the hope it will retain/gain value.
Blockchain gains entry digitally where most people are today, making transacting easier, retaining information safer, planning into a future where you are your own banker, contracts, services offered.
Never invest everything in one place, none are that safe!
