None, really.  It has more to do with public consensus than anything else.  Assets like gold and real estate arguably have the strongest value consensus behind them, just given historical momentum.  Similarly, Bitcoin has stronger value consensus than Dogecoin.  But lets not kid ourselves .. The internet has been around in some form for roughly 30 years.  Bitcoin has been around 5 years.  Dogecoin, a few months.  On the human timeline, these are mere blips.  They are all nascent technologies and there is little reason to assume one will definitely triumph over the other given such short incubation periods.  Everything, and I mean everything in this cryptocurrency universe is still in beta testing.  Invest accordingly.
