If one of Bitcoin weakness is scalability and if DPOS solves that issue, why don't release a DPOS coin that has the sole purpose to be a BTC competitor? That say, a coin which is useless besides that you can send and receive it.
I know you will tell me that it's logically better to add more features, but maybe less is more in this case. Maybe people will use DACs but not use them as money because they don't like the uncertainty linked to the viability of the business model of each DAC.
Or maybe people won't use DACs because of wathever flaw generated by the layer of complexity that DAC's additional features are bringing, but they would use a DPOS coin because it's scale better.
