BTC should see big bullrun based on past performance...
But in the middle of bullrun never happened something like this year when China banned miners, what caused big decline in mining hashrate.
Seeing that we have hashrate on the 2019´s level is not very bullish.
On the other hand from long term perspective it is better to diversify mining to another countries so it can be more decentralized.
Bullrun continuation depends also on that how fast will mining migrate to another countries and how fast will hashrate recover...
You can see hashrate decline also on hash ribbons indicator which is still in capitulation mode.
