What is your take on the alts that serve a secondary purpose like Namecoin or Protoshares?
My 'take' on them is that they would be useful if they built their services on the bitcoin blockchain, where all the hashing is done.
5-10 years from now, we won't be calling it the "bitcoin blockchain." -There will just be one single blockchain on this planet and all of us will have our money on it, our legal contracts on it, our notarized documents, our DNS functionality, our IOUs, our credit reports, etc... It will be so useful because it is so much more powerful than all other forces that could attack it.
Altcoins will still be cute little toys and spare parts pools for bitcoin, but 100% of the value of a blockchain is in its' strength.
If you really want to try to estimate the 'true worth' of a bitcoin, think of it as a stock issued on a company that holds everyone's money, legal documents, credit reports, DNS, etc... Effectively.
How much would 1 share of a stock be worth if a company that did all of that, without the ability to be corrupted, and even had the power to tell regulators to go F themselves? And you knew there would never be more than 21 Million shares issued?
A hell of a lot more than $1000. Can Berkshire Hathaway do even half that? 1/10th of that?
If you really want to understand this stuff, listen to everything this man says:

Andreas has tons of YouTube vids on bitcoin, and they're all worth watching.
