Not sure where those numbers came from. A lot of BCN traded on polo in the first month. Here's is the daily graph. The first scale line on the vertical axis is 20 BTC.
Ah I see my mistake - I forgot to change my candlesticks scale to 1-day, thanks for catching that.
could thos things be generated so they look real (transaction times etc, the visible things in CN)?
They could be done with a significant degree of randomness, I have no idea how easy it would be to tell if it was statistically random or had a patter in it. Worth some investigating at some stage, no doubt.
