The value of bitcoin is the entire physical wealth of the world divided by the market cap of bitcoin. The altcoin is worth all the abstract/intangible value of the world divided by their market caps.
I know the first couple pages of this thread are awesome. I definitely didn't think it'd be this high but I definitely thought it'd be up to $5000. The reason why it's going this high and why this isn't a bubble is because bitcoin is basically solving the biggest problem in the history of the United States: a solution to the centralized banking system. This problem has been magnified in the past 100 years as money has started to become more and more abstract and electronic and peoples entire lives can be destroyed simply by swiping their card at a cash register, businesses can be destroyed simply by not having an emphasis on online security, and people having to pay to get their money, wait to get their money, and pay to wait to get their money.
I just hope that when cryptos do take over from government backed fiats that core developers use transaction fees for roads and infrastructure.
