It'll be interesting if there is another strictly better distributed cryptocurrency anytime soon.
I've thought about that from time to time, and I cannot imagine any disadvantage of Bitcoin that can be improved without changing the essential nature of the currency.
Sure there are some minor issues. For example, an average block time of 10 minutes might not be optimum, but these are relatively insignificant things won't make-or-break a currency.
There are major issues too. For example, that it's difficult for non-technical users to secure their wallet. But all the major issues seem to be amenable to incremental improvement. It's just a matter of people putting in enough time and work to fix these things.
When you add Bitcoin's "first mover" advantage to that, I think it's highly unlikely that another distributed cryptocurrency will overtake Bitcoin any time soon.
Because Bitcoin's fundamentals are strong, a pledge of allegiance is irrelevant. And if Bitcoin's fundamentals were weak, a pledge of allegiance would be useless. So I respectfully decline Atlas's invitation to "put 95% of my life on it".
