I think the main problem with Bitcoin is people is too dumb the see the necessity for it, so most people will keep using fiat currencies because most people don't have a problem with it, only people whose see a real necessity to use Bitcoin (beyond buying it and holding as an investment) will actively use it. Other than that we'll need more time to see the fiat system collapse more to get Bitcoin in the starlight. And anyway people will end up using it even if they don't know they are using it so we already winning as early holders. You are basically investing in the base of the next gen infrastructure by holding BTC.
I agree with this one. People were always going with that one "if it works, why change it" and this is exactly the case with Bitcoin at the moment. Look at the situation in Cyprus and Greece and how the people took interest right away in Bitcoin.
So, the future financial crisis will just speed up Bitcoin adoption. I am not saying that people wouldn't gradually see a use case even if the crisis were not ahead of us, it would just take more time for adoption.
Luckily, or unluckily for all of us, there will be some financial storms ahead of us in the near future.
