Hey smart investors and forward thinkers, I hope some of you respond.

1. What determines the price of each BTC? Is it purely based on supply and demand... or is it assessed by dividing each bitcoin available with the market cap? Do the exchanges set the price automatically or do the miners set the price themselves? I'm still not clear on how this works.

2. Say in 100 years when all of us are dead, along with most of the initial bitcoin holders... will all these bitcoins be 'lost' because no one will have access to our private keys? Do you think there will be some sort of problem around this?

3. Do you think bitcoin will come into play during the next US presidential election? I'm hoping by then even more people will be aware of bitcoin and there will be more debate around it. Whoever has the best policy in favor of bitcoin will have my vote.
