Bitcoin spikes 70% in a month; nobody knows why

Looks like algos picked up on log scale trendline break (Oct 25th-27th or so) from long term consolidation, thus the acceleration in the past 30 days. Buyers pile in. Price goes up.

Yesterday, there was speculation it was due to China [1], increased legitimacy [1], or a ponzi scheme [2].

And that's why trading needs fees, otherwise craziness follows.

I can find my friend and give him $5. There "needs" to be a fee attached to this?
