Great post.
The main issue is (in the crypto space) people think they're investing when they're really speculating on coins they think may go up (x2 or x10) in value, over the short term.
Thus investing on something for 3-5 years scares them shitless.
Eventually the right type of investors (and investment) will gravitate towards Steem/ Steemit as long as the the community keeps growing and delivering things of value, as it's doing.
