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.
You should get used to the changes that you see in the price of bitcoin because that is the consequence of having bitcoin but you should be happier that you have bitcoin because with those constant changes in price, it might be a huge change for a higher price where you will benefit a lot and you will create wealth because of it.
