Another theory about why there is so little resistance to the current climb:
1) many of the largest bitcoin holders were criminals and/or money launderers; and
2) ^ have been scared away from the major exchanges due to regulation and government actions over the summer.
i would have to go with this and add that...
some never reported their btc income a couple years ago when they mined it or were paid for services (maybe didnt know what to do with it and it was monopoly money at the time) and don't want their btc showing up at places that have instituted KYC... you know what happens to money assets that you hide from the US govt after 3 years right... not saying it is right but that's the way it is...
