Eventually, the price will level out and it will become a investment that is as boring as gold.
Is this a bad thing?
I don't really care if bitcoin becomes a world currency, a payment system like paypal, or a digital gold. I'll be happy as long as functions and continues to be a reminder that an independent system of exchange can also work. That not everything has to be registered and ask for permission to be used. That you don't need a license to trade with other people. This is what's important for me.
