Why invest in Bitcoin?

There are only 21 million Bitcoin, and as time goes on, they become harder and harder to mine. Always invest with money you don't mind losing by the way. As with any market, nothing is for sure. Throughout its history, Bitcoin has generally increased in value at a very fast pace, followed by a slow, steady downfall until it stabilizes. Dont take anyones advice about what will happen with the currency, do your homework, learn about Bitcoin and come to a conclusion. Personally, I believe we are just starting, but thats my own opinion and you shouldnt consider that as investment advice as well.
