Similar to the recent subject about when should we start to measure BTC's price because of course, one of the very first transactions to buy two pizzas for 10k bitcoin might not be as representative as prices a few months down the road when larger numbers of trades are allowed and even locations for conducting such trades become more common.. so in that regard, there is a kind of product of the number of transactions and maybe the passage of time, and I do have some troubles gravitating on any price analysis that uses 2010 data because it seems so sporadic.. but it seems by the time that we are getting to 2011, even if the BTC price discovery is relatively immature, it seems fair enough to start to use that data rather than waiting for 2013 or some further down the road date - at least in my thinking.
I'd agree. I think that, barring contrary evidence, that is perfectly fine to consider as the seminal event in the price discovery for Bitcoin. I've always been wary of wanting to throw out data because it doesn't fit a narrative.
As Wayne Gretzky said, “I skate to where the puck is going, not where it has been.”
When trying to predict "where the puck is going?", it's important to consider its current position and its position 1 second before.
Because you can extrapolate from that data.
Knowing the puck position from 5 minutes ago, or even from the start of the game would not be very useful...
