I wish i could say i was drawn to Dash because of this video :
https://www.youtube.com/watch?v=Kmb8bo-n55Abut that would be difficult as that video was made in 2016 and i got into Dash end 2014 (at the top of its very first and very large peak).
At the time i was looking for altcoins to mine with my GPU and i looked at several altcoins before arriving at Dash.
Even at that time it became difficult to mine Dash as there were large GPU farms operational already and also the idea of having my computer
constantly on with 100% workloads on the GPU started to worry me.
In that period the masternode concept was still in its infancy, but i got drawn into it and saw the potential there as the original payment schedule
had masternode payments go up to 60% of the blockreward and that certainly got my attention.
I even made a thread about it on 17th of november 2014 :
Dash's Masternodes, what are they ? how many are there ? why should i care?
https://bitcointalk.org/index.php?topic=860067.0Later on Evan Duffield, lead developer of Dash introduced us to the concept of having a decentralized budget paid directly from the blockchain, splitting the blockreward into
the 45% Miners / 45% Masternodes / 10% Budget. This was really a brilliant move as it gave Dash independence of budget, Dash could now focus on developing and attracting the
the tools and services which it needed for expansion. With the budget coming straight from the blockreward, the masternode owners also got the important task of governing that budget
by voting over those budget proposals.
The primary reason though for investing in Dash was the feeling i could trust this dev-team and its lead developer, who gave up so much of their own anonymity while working on a privacy-focussed
cryptocurrency (Dash grew to be much more then that of course but end 2014, it was really just focussing on privacy). I got to know the dev-team by participathing on Testnet and saw first hand
the drive these guys all have .. the drive to really make Dash mainstream usable digital cash.
