Conclusion
Both digital currencies’ status as money and the distributed
ledger technology used by them have potential to develop
over time. Most digital currencies, at present, deploy fixed
eventual money supplies, although this is not strictly an
essential feature. Usage of digital currencies is presently very
low and, as currently designed, there are a variety of incentive
problems that are likely to prevent their widespread adoption
in the long run.
They also draw the conclusion that bitcoin style has no future for its fixed supply and costly mining.
Bitcoin—>fixed supply—> deflation/volatility---->death
Bitcoin---->PoW----> costly operation—>death
but I’ll salute bitcoin for its leading and absorbing fire power in this battle, when bitcoin fall down, let’s give it a grand funeral. 
ehh, how to insert a youtube video?
