The first hurdle is to get an investor that understands blockchain and there's not many in that category. If the investor is looking for a buy-and-hold then that's a very different conversation to one looking to make their money work for them. There's opportunities on steem to earn (e.g, vote selling, delegation rental) but crypto is still way too risky relative to the returns you get for most investors. And, taking advantage of those opportunities requires a little bit or work/tech knowledge.
I'm more likely to discuss investing in teams building side-chain projects on Steem. In that sense, steem is the background fabric to the project. I think it's an easier conversation to have since side-chain projects are much easier to understand in terms of standard investing criteria. The technical bits of steem then become largely incidental.
