I was lucky enough to see the potential in Dash when Amanda posted the very first Dash Detailed video. Sadly I wasn't able to get much then or even now so I haven't gained much in the way of profit as others have, but this is my fav concept so far, no others are close in my opinion.
It's not enough to have the best tech, people need to know about it too and the distribution of the block helps a lot in that respect. Also, when the Bitcoin mining difficulty rises beyond profitability, who's going to confirm the transactions again?
