Realistically the market will be small to start and hopefully grow organically like any new user base.
There are no expectations from the community to kill DNM. That's just crazy. That's like the 95%+ of coins out there trying to kill Bitcoin (which almost all think they will

). It's not realistic. Shadow isn't trying to replace the DNM in as much as it's not trying to replace Bitcoin.
The market will offer new ways to do business around the world. But all the current ways will keep chugging along that's for sure. Hey, just today I used cash to buy coffee. And drew a picture with a pencil on paper. Those still work perfectly fine.
Just comes down to what do you want out of the tools at your disposal.
