the only blockchain application (besides currency) i know of that lots of people use all the time is Steemit (you can use it for free without buying any digital currency, which makes it a great onboarding ramp into the blockchain space for new folks). apparently BitShares and Steemit are #1 and #2 for blockchain activity, which is amazing because you don't hear about either of them having scalability issues.
Bullshit.
People "use it" because they are monetized links.
Steem is a rigged crooked scam coin by a known scam dev.And the answer is none.
These Investards do not "use" the tech.. they invest in ICO coin schemes for ROI's.. nothing more.
Nor do they care if the general public "uses" the tech either.
