Well it is not much for miners.

July 2019 price was 13k or so.

This 19.2k is sort of that due to diff increases and 1/2ing

For me a miner  25k-30k  December 2020 =  13k July 2019

but when we got to the price of 13k in  July 2019 we tanked for quite a while.

19k is very sustainable number for mining.

30k right now is too high to stay.

Think what I do mine and hold eventually selling on upswings at tiered levels.

So if a big time miner has hodl hard and long he will dump like a mofo at some level.

The level is not 19k
The level is about 30k for me.

Dump my larger holdings at 30k and hope for a strong correction.

There are major mines that hodl and could dump at the 30k level.

Remember they will earn coins back via mining and be very flush.

I still think this cycle above can happen at the 30k level.
