What a crazy obsession with China we have here on the forum, and what nonsense I read especially in my local media that this is the end for Bitcoin - as if China is the only country in the world where Bitcoin can be mined.
I think there are two sides right now, and I find them both amusing
- the ones claiming bitcoin will be dead without China
- the ones claiming China will become a 3rd world country without Bitcoin
Both going way overboard with everything, I don't know why people can place so much importance on a single things where there are thousands to pick from
and for your information hashrate when price was $30k last time was 100 exa hash and today that price is a little higher than $30k it is 90 exa hash (approximately) so that is a 10% drop not 80%-100% as you said.
The last time the price was 30k and there was no sign of China doing anything was in January, at that time we were flat at 147.46 EH/s, 149.05 EH/s, 153.41 EH/s for a month, so that price was able to let miners mine with that much gear, now we're seeing under 90 exahash and it's not over yet at same level prices with far more efficient gear being shipped in three batches since then.
Also, 10%? Nope. The previous retarget was on June 13, the price was 35k and now we're looking at a
26% drop..
On May 23 the difficulty was

Right now we're looking at :
Next Difficulty: between 14602665475646 and 14659149779937
That's a 40%, remember that the first news about the ban
started to appear in May two days before that so the ones with good connections probably were already at the border by that time.
