Interesting. Judging by these metrics, Bitcoin should hit a new all time high sometime in the next few months. IMO, I don't really think that is realistic though.
Consider the sample size... the stock market has been around for much longer than Bitcoin. Although the Bitcoin graph may be true so far, as the sample size grows I expect to see the Bitcoin graph mimic the Stock Market.
Furthermore, you can diversify holdings within the Stock Market, but with Bitcoin there is only Bitcoin. Perhaps by that metric, in the long run Bitcoin will perform worse than the Stock Market. Of course you can diversify into alternative cryptocurrencies, but the graph doesn't reflect that.
