BitCoin is both an awesome idea and a very dangerous investment.
If you got in to BitCoin when it started, you could be a millionaire with less than $1000 invested.
The idea of BitCoin is awesome because it is unregulated by governments, but this is also why it is so dangerous.
BitCoin is in a huge bubble at the moment, where the value has been skyrocketing. Just as it does in every economy, eventually it will crash, and a lot of people are going to lose A LOT of money.
At this point, my suggestion is stay away from it. If you got in when it started, you should probably start selling off your bits. When the bubble pops, all the fun will be over.
