Possible mass accumulation of Bitcoin happening at these levels

I've been watching the combined order book very closely and every time the price approaches 21k area or dips below that, the supply/demand chart becomes very unbalanced with demand significantly outweighing supply. More buy trades come in (a lot more) and the price level holds.

This has happened at least 4-5 times this past week, I believe some large institutions are slowly accumulating Bitcoin at these levels, and will probably continue to do so if price dips more. The S&P doesn't look very attractive at its current level and a long term play on BTC certainly has more upside potential, worthy of allocating a portion of their capital into.
