As long as Bitcoin stays open source and voluntary, I don't see a problem of anybody funding its development even if it's a CIA or JPMorgan. What we should fight for is to have an open market for alternative currencies.
Cryptocurrency is best served as a natural monopoly. Bitcoin will likely be the only popular cryptocurrency. It's not a like it or leave it type of thing. We do no not need it controlled by the government or the largest bank.
It doesn't have to be a monopoly.
If we look at gold, for example, one might argue that it was a natural monopoly on money, but I would argue that silver (even though less valuable) served as money as well.
And we already have "silver" to Bitcoin's "gold" - it's called Litecoin.
...
I'm going to stick with Bitcoin and defend it until death for the interests of those who want a protocol that can't be easily changed. I am not going to Litecoins, Cosbycoins or Free Speech Zone Coins.
Thanks.
