I have seen this chart before and heard that we are still in 'early adopters'. I frequently ask
strangers - at a park, in line, party, etc. if they have any BTC and most do not even know what it is. Those that do know think it is 'internet money' and have no idea of the world changing blockchain ledger smart contracts, etc. At age 69 I am wondering how much change I will see, I expect a lot!
