Great video! And writing :)
Dash is pretty much an improved version of BTC, I would say that Dash is BTC 2.0.

These BTC transactions that takes hours / days is not gonna work, and as you say long BTC adresses and QR codes aint super userfriendly aswell.

Luckly Dash have taken care of these problems and even took it further then that, upcoming Dash Evolution is gonna be amazing!

Upvoted and resteemed! :) Take care
