It's too hard to time an investment with a 13 week window to get out. Hard to pull out in this case also means hard to put in.

Dude, believe it or not, I was having that same exact thought today, in a moment of reflection about Steem in the crypto space! I was thinking about writing something about it, but you beat me to it. I agree, it's a very important aspect of this platform and big investors are surely be turned-off by that. In a moment of crisis, investors must act fast, but with their capital being tied down to 13 weeks, it's not appealing for them at all. Steemit needs to rethink this strategy, if they want to focus on investors; or focus on the regular non-wealthy folks to increase the user base and activity on Steemit. When the user base is huge enough, perhaps it would convince the investors to put their money (and faith) in Steem for the long term.
