I certainly hope you're right! However I feel like the way you're jumping to this conclusion of 500,000 a btc is a bit too simplistic. There are many other factors involved in price besides worldwide adoption. Regulation, mining, human nature (which is unpredictable) and possible problems involved with bitcoin that have yet to be discovered. It's not totally unreasonable to see 500,000 a coin at some point but I don't see it anytime in the near future. Maybe 30 years from now but we also have to take into effect the rate of inflation. What will $1 buy us in 30 years? I love the bullish outlook on bitcoin but I think you're just a bit too bullish. Just my 2 bits though. I hope I'm very very wrong
