Allright, even if the exchange rate won't go up it's still "$73 - electricity" profit 
The supply is generated by miners, so it's tightly related to difficulty. Demand is not related to difficulty though. But bitcoin is designed to be limited to 21 million coins. So unless something bad happens it's really attractive for risky investments.

Yes, demand is not related by difficulty as I mentioned. People starting to swap difficulty for demand is ridiculous. Also, just because something is limited, it does not automatically give something more value either without demand. Demand cannot be created by making it hard to make bitcoin which is what difficulty is.
And noone should be taking any investment advice from anyone here on the forum. I have a series 7 license to sell and trade stocks and I don't give out advices. With so many uneducated guesses of recent new young audiences of bitcoin, I would also read all threads with a grain of salt. Myself included as well.
