The biggest problem with Bitcoin is volatility. Hands down, you can't argue that., and everyone knows it. Every new investor invests in Bitcoin with hopes that the price will rise, not to use it to buy things. Why would you spend something that could be worth 10x more the next day. Is there a way to add something to bitcoin to make it more stable, or do people not want it to be stable? Eventually either Bitcoin will change to become stable or a new currency will come along and take over. So has anyone come up with a way to stabilize a currency without a central authority? In the end I think Bitcoin will fall, and a new currency will take its place because there are too many flaws. Bitcoin is volatile, the name Bitcoin could be be much better, and it is not very user friendly at all. But it's paving the way for all other cryptocurrencies, and doing a great job at that.
