Bitcoin "Rainbow" Price Chart(Log Scale)
The Rainbow Chart is not investment advice! Past performance is not an indication of future results. The Rainbow Chart is meant to be be a fun way of looking at long term price movements, disregarding the daily volatility “noise”. The color bands follow a logarithmic regression (introduced by Bitcointalk User trolololo in 2014), but are otherwise completely arbitrary and without any scientific basis. In other words: It will only be correct until one day it isn’t anymore.
