Saw this on a youtube video and wanted to track it...seems too easy, but every bull run BTC has made, if you fibonacci it from high to low, look at the 4.236 extension, that becomes the next base value for it. So even though we currently at around 50k, the base value after this bull run, based on what BTC has done in the past, it should base out around 70k. After all bull runs, BTC has also seen significant draw downs, up to 80% like we saw in 2018, sometimes only 60%...so if you're trying to figure out the high based on that. These numbers are exact but pretty close = 200k to 70k is a 64% pull back. 300k to 70k is a 77% pull back...have fun with that, haha.
BLue horizontal lines are halvings.
