Why are you using his year old prediction?
There is another in his telegram channel and it is much more actual:

And here is his last comment (week ago):
There we have a weekly ma200 for 4000. We can visit it. And that fits the picture above.
So, according to this traingle picture we will see something around 4K till next year.
I am starting to think that maybe, new ATH won't happen any time soon. (in the next 2 years) If this shit graph becomes real, you should target the halvening after this one. Not the next one in May/2020. BTC can always surprise us suddenly but I am starting to lose hope.
It would make sense too. The bigger the triangle, the longer we wait for the next run. 20k ATH triangle was a lot bigger than the 1k ATH triangle so the bowl should be wider...
