I'm not a fan of Dogecoin, but I like their marketing.  All bitcoin needs to is make sure that the other 75% who do not know bitcoin at least here the name.  Because when I heard about this technology recently, I was hooked right away and I believe that will be the case for many many more.  Then the ones that pick if up right away can help explain the benefits to the rest.  Its a definite game changer but can't just sit back and wait for adoption or a more savy marketer with an inferior product could win.

The biggest thing that I always hear as a negative is the money laundering aspect.  Now it seems to me as if it is the exact opposite.  I know its anonymous but can be eventually tracked once you have the wallet ID, right?  Law enforcement can look up all illegal transactions on the blockchain like they did with silk road.  Whereas nothing would be better for Money laundering than the us dollar.  You can pass those to anyone with absolutely no proof!!  It just seems to me like you could argue there are some drawbacks to bitcoin but money laundering is not one!
