go up and you can make some money or they could go down and you will lose money I guess the risk is part of the fun though lol.
"Investing" in bitcoin is not really investing, since bitcoin is money it is saving. The real possibility that bitcoin can appreciate, is a one time event while bitcoin is being implemented. When bitcoin is fully implemented, you have the option of taking interest from lending, or invest (buy capital goods with the intent of producing something of value).
