[opportune]

I wouldn't say hostile, more skeptical. I think bitcoin and some altcoins (siacoin and ethereum in particular) are really cool technology. But I don't have faith in cryptocurrency as anything more than a digital remittance system with side applications in money laundering, the drug trade, etc. And as of right now I have yet to be proven wrong about this. Bitcoin in its current state won't be able to replace normal transactions due to fee and speed issues.

I've also seen a shifting of goalposts within the bitcoin community from the utility of bitcoin being a censorship-free digital currency to a digital store of value. Personally I am not at all interested in the concept of "digital gold" because there's nothing inherent about bitcoin that makes it better digital gold than other altcoins.

Of course, there's also the fact that new altcoins seem to constantly be improving on each other. This is good in general, but as a side effect it makes comitting to one single coin seem like a short-sighted move.

That said, I would love for a cryptocurrency to be able to scale to the point that it becomes a viable part of the global economy. It would be amazing for privacy and anti-authoritarianism. At present, bitcoin cannot scale to this level, though.
