BITCOIN 2015 support is still holding

BNC:BLX   BraveNewCoin Liquid Index for Bitcoin
For my first technical analysis published on Bitcoin I wanted to share with you the theory of the 4 year cycle. From this analysis, we can speculate to see Bitcoin going to 200k.
Please, share with me your ideas and why this is a realistic or non-realistic target.

Using the Fibonacci circles , in 2015 you could identify a new important price level. Just one year after the beginning of the bear market in 2014. In January 2015 you could see forming a new bottom. By connecting those two points with the Fibonacci circles it's clear that the 4.236 Fibonacci level indicate today's support for the 2021 bull market.

The Black line indicates the top of the bull market as it was exactly the case for every new market cycle. The 4 year market cycle seems to be aligned in some way with the Halving that is happening every 4 years.

Thank you everyone.
