If you look at the weekly chart for BTCUSD you will see there has only ever been 2 crossovers of the 7 EMA and the 50EMA.
First crossover was in January 2012 when BTC was $4.68 - It went on to a high of $1177 in November 2018 before coming back down. Thats 251x move on BTC = 20,510% Second crossover was in October 2015 when BTC was $290 - it went on to $19,764 in December 2017 before coming back down. That's a 68x move on BTC = 680%
We are now at the third ever crossover, in 9 years, of the 7 EMA over the 50 EMA. If this was to move even a 50x gain we would be looking at $266,000 for BTC within a few years.
