I don't see any serious problems for today, except too high volatility even for BTC. I'm absolutely comfortable with using it, but I face difficulties because of constant changes of its price.
I also think that even now people feel it easy and comfortable to use bitcoin for their different activities. May be in few places where people may not allowed to use bitcoin for different purposes feel some disturbance but still i think that in such places whee bitcoin is consider as illegal still there people feel it easy to use bitcoin for their different purposes.
