If BTC/USD finishes above 40,000 for this week, that would mark the 4th in history that eight weekly candles in a row are formed.
This happened during the 2nd bull market of 2013 which took Bitcoin from 50 USD to 1200 USD.

I happened in the end of 2015 which marked the transition from Bitcoin's bear market to the 2016-2017 bull market, the bull market that took Bitcoin from 200 USD to 20,00.

And last time it happened was in the above-mentioned 2016-2017 bull market when Bitcoin crossed the ATH price reached in December 2013. The following six month, Bitcoin went from 3,000 USD to 20,000 USD.

So two out of three times, eight candles have been followed by exponential bull markets. And one time it has marked the peak of a bull market.
