Wow, short and to the point.

I still remember BAT ICO getting to $200 transaction fees and thinking: 'why has nobody solved this yet'

Well, I am glad that I learned about Bitshares soon after and hope that more and more people will see just how far ahead it is.

Elevator pitches are never easy, it really makes you think what is really important. I think you conveyed the really important part: Bitshares is fast, cheap in fees and scalable while easily upgraded for later requirements.
