Rpietila, your analysis is bad and you should feel bad.
I like y'all's style.
You're either trying to prove a point and cherry pick your data accordingly, or you're honestly too naive to see that in late 2013 you simply cannot take data from one exchange alone and then draw grand conclusions from it.
Honestly naive sounds better to me. I had just gotten to use Bitstamp instead of gox for the analyses, and now the china thing steals the show. It was not intentional to bias this, and I have not verified the "corrected" figures myself yet either. It is very possible that you are right.
I'm too lazy to draw in a nice moving average, but I trust you can see the rough trend yourself: there were indeed two spikes in btc volume compared to which we are somewhat lower now, but not drastically so, and certainly we're not lower in btc volume than in the beginning of the month. In simpler terms: btc volume is stable or slightly going up.
This was not the point. The point was to show that there is markedly less volume in higher
prices, compared to lower. It is not the same thing as higher volume over time. The point was to visualize (e.g.) that if only 2% of coins have been traded at over $700, the price level is not yet very established, and will not be supported by buyers if the selling intensifies.
Main thing, as is always the case with fast runups, is the lack of support levels. We have one in $400 and the next one in $190-$266. I don't believe we will ever see the latter, but the former is very much a possibility. All this talk about bitcoin "entering mass adoption" and "everybody talking about it" was there in May. Perhaps we now have 10x more substance, but then again the price is 10x higher.
And USD volume paints a stronger version of the same picture, as is to be expected with the hugely increased per coin value: two spikes earlier this month, and we're slightly below them now, but overall it's going up.
Every spike in USD volume can be the last. We are multiples higher than in the beginning of the month. I appreciate your willingness to delve into the matter but it does not change my very cautious outlook. As for psychology, when everyone thinks that it is time to buy, the time to buy has just ended.
To repeat: by "very cautious" I mean that 80% in bitcoin is warranted but 90-99% is not in these market conditions. If you have less than 80%, then you are actually more bearish than me by your actions.
