As a techie who's been following bitcoin and disapproves of their libertarian ideology, I like the Dogecoin attitude. It's all a joke. It's like it's not serious. It's like people know that you're not going to replace all the money.
Funny enough, that attitude may make it more successful in the long term. History has shown many times that it's not always the 100% dead serious who make it, but those who are just, well...making it up as they go along.
Lots of truth to this from a brand perspective, but the underlying technology of Dogecoin is pretty serious, it just happened to be deployed in a playful way. Not unlike the way that gaming technology or 4chan’s infrastructure is serious.
we can have serious hearing in Senate on BTC with outcome rules [almost] killing or seriously affecting it. Having a hearing and SEC/FBI enforcement on Doge? With Doge as a witness. Put you paw on the Bible and repeat after me ...
Well...there's that one operating system out there that got pretty popular after some guy in Finland posted it online. Name escapes me at the moment, though.
Crypto-currency is not decentralised by nature. Bitcoin, dogecoin etc. are just one model. There are other models for crypto currency that involve issuing banks and have other advantages - offline transactions and no crazy waste-of-electricity hashing races.
For BitCoin, it'll be transaction fees. In order for your transaction to be proceeded (which requires a form of mining), you'll have to pay a small fee.
