The rate at which new bitcoins are created is algorithmically cut in half roughly every 4 years (210,000 blocks). Bitcoin has gone through two halvings to date; in November 2012, and again in July 2016. Since blocks are generated every 10 minutes on average, and starting at 50 new bitcoins per block when the system was launched in 2009, this creates a very well-defined supply curve. The stability of Bitcoin's monetary policy a key differentiator versus other crypto assets.
This is a number ranging from -1 to 1, which represents the degree to which movements in the two assets are historically correlated. Specifically, OCFX is calculating the Pearson Coefficient over the daily returns of the two assets. This is calculated over the time-range the chart is set to, and will be re-calculated if the chart's time-range is changed.
A negative number indicates that if asset A moves in one direction, asset B has historically most likely moved in the opposite direction. Similarly, positive values indicate prevelance of same-direction moves.
The Bletchley 10 is composed of 10 of the largest cryptoassets, weighted by marketcap. As such, it tends to track the 'large-caps'.
The Bletchley 20 is composed of 20 medium-capitalization cryptoassets.
The Bletchley 40 is composed of 40 small-capitalization cryptoassets.
Together, these indexes give good at-a-glance understanding of how large-caps are performing relative to medium/small-caps over the past 24 hours.
