One of the most fascinating parts about bitcoin is the ability to make money from buying it. Obviously anyone can go and buy bitcoin for profit, but businesses large and small are also doing this and making tons of cash in the process. For example, MicroStrategy is a software company that holds over three billion dollars in bitcoin. Just take that in for a second, three billion dollars worth of bitcoin...
Talk about making profit from bitcoin, mere 5-10 percent positive price swings must result in hundreds of millions of dollars in profit. Even smaller companies are making a killing, just on a smaller scale. All I know is that as soon as I start my company, I am going to hold a large portion of the equity in bitcoin.
