There are people who are worried about hash-rate, price of the bitcoin, if mining is still profitable or not but yes we are too early to talk about all these. One thing is for sure that there will be a balance as it was always.

We are not in a position to conclude anything at all. Whatever we are seeing is temporary. If the price increases, the miners will come back to business again. And if the price goes below 8k, we will see more miners closing off their operations. Yes, one week will be good to analyze the situation again!

There have been 123 blocks mined since the halving, and it took 20 hours and 21 minutes to mine them. This gives an average of 9 minutes and 55 seconds per block. Between the halving and the last difficulty adjustment, there were 1007 blocks mined in 6 days, 15 hours and 18 minutes, for an average of 9 minutes and 29 seconds per block.

If there has been a drop in hashrate in the last 20 hours (it's not a huge amount of data to go on, and so random chance will fuzzy the numbers a bit), then it has been small and likely hasn't dropped below what the hashrate was when the difficulty was last adjusted. If miners do start feeling a pinch in their profits, it's likely to be over the coming days to weeks and not immediately though, so it's too early to draw conclusions.

At both previous halvings, it was the second difficulty adjustment after the halving where we saw a significant decrease in difficulty signifying a drop in the hashrate.

Block 211,680 saw a 2.00% reduction
Block 213,696 saw a 11.59% reduction

Block 421,344 saw a 0.04% increase
Block 423,360 saw a 5.43% reduction

If the hashrate is going to be affected from this, it's too soon to tell.

we can't even measure hashrate with that kind of accuracy and in such a short period of time to want to conclude whether any miner at all has shut down or any new miner has come onboard. specifically when the changes look small on these types of charts they are within the acceptable error range.

Possible, they may have done some risk assessment and how well to manage it. So we can assume that they have replacement ready to continue to shop and used old machines to mine altcoins.

That's why we haven't see any noticeable drop in the hash rate post-halving. But I will say it's too early to conclude, maybe the impact can be felt in the next month or so.

I have the same feeling, i was expecting a massive drop down on the hash rate, from what i was thinking lot of miners would start working without profit and the best option should be to turn them down, but as we can see the change wasn't that big, i think we will have to wait one month and after that see if there is a real impact.

think of it this way
there is a base line of say 80exahash which is mining farms(big industry) miners always running because they hold year long contracts for purchase of facilities equipment and also they do 'wholesale' deals of buying electric from the grid. they will run no matter what. they dont play to the whims of daily activity. they are in it for the long haul

the amount above 80exa. well thats a mix of smaller commercial miners and also home hobby miners.
these lot of say 50exa (the wavy part at 90-140) jump in and out all the time, only mining when its profitable

Well, you would certainly hope so. It's not like the halving was unpredictable - we've known it was coming for a decade. Any responsible miner should have figured out and implemented whatever steps they needed to take to remain profitable after the halving well in advance.

The most accurate data we have suggest that 74% of energy used in bitcoin mining is from renewable sources. The main cost with using renewables is the set up fee, but once you've paid for the solar panels, wind turbines, whatever, then their upkeep cost is minimal. In these cases it makes no sense for miners to stop mining - they've already paid to install the renewable generators and can't get that money back, so turning their ASICs off would just be wasting free electricity.

https://diff.cryptothis.com/ has good stats.. and predicts -5%
So if we assume that is from the second half of the period then lost about 10% of hashing power due to the halving.

Also interestingly this is predicting a 17.5b difficult average in Q3:

although has tiny volumes so not sure should take much notice!

Which implies that the difficulty will raise by 20-30% over the quarter to about 20b. (as average is 17.5b).

So should be above the 16.5b seen in March by end of June.
