I've thought seriously about investing in BTC and/or mining but I just can't do it.
People seem to forget that the primary function of BitCoin is that it's a currency, it's meant to be used to buy/sell goods. The problem is, you have so many people using it as 'investments' that it becomes so inflated that people don't want to spend it and merchants don't want to accept it. Too much risk with the price bouncing around hundreds / thousands of dollars a day.
