It's more like a random address found online, i checked the second address in that page and there's no balance on it based on block explorers yet on the site's screen shows it still has balance.

Only greedy newbies will likely to fall on this cheap scam attempt. Btw where did you found this site?

It's obviously just an attempt to scam people. If you have access to private keys for a wallet, why would you sell the funds x10 cheaper, when you can just use an exchange and get the best rates possible? Stay away from this site.

The motivation? To make money.
More efficient gear will get you more hashrate for the same power costs while also driving up the difficulty.
That is how the system works.

Some miners with older gear that is less efficient or miners with more expensive power will drop off. Will others take their place is the question. And that will not be known for a while.

Also, there are people with deep pockets who are speculating. Loosing some money today thinking that BTC will 2x in price will also keep people mining or bing in new miners.

Do you mean this announcement from Telegram  ttdsales  #66   

----
I have been doing a deep dive into the range submissions from the user kafeitianshi.  He ran very hard for a couple of months but I have never been in communication with him.  There was a vulnerability in the system that would allow a user to kill either vanitysearch or clbitcrack right after the PoW key was found then the client would submit for credit,  restart, and continue.  It seems this is how all of  kafeitianshi work was submitted.  I was able to determine this by looking at the times between when a range was requested and when it was submitted.  Under normal operation this would conform to standard deviation.  In this users case the time taken between ranges was just as random as the location of the PoW keys in the respective ranges.

This vulnerability has been eradicated in the newer clients.

So the bad news is that I need to mark the 227,357 ranges as unchecked and we take a 0.67% step backwards in overall completion.

The good news is that the ranges scanned on the pool are more accurate then ever.

I will continue to investigate range submissions for any other anomalies.

Only the puzzle creator knows the private key #66 and can do this, but I don't think he would be so boring to do it
 

Yeah, it exists but that's only a sad fact. Ordinals, runes, epic sats, these things don't exist, they are made up things to make money out of thin air. Giving value to all of these is like giving value to grass where Messi fell down with his face. It's like giving value to socks and pants that Messi wears because it's Messi. This is not normal.

You are right, this is just a waste of bitcoin blockchain but like you said previously, it's true that BRC20 exists and has a huge market. I intentionally ignore it because I believe it's scam, I don't find anything valuable in it and I think its created for money laundering and for scamming people, that's why I don't join and will never join BRC20 market.

The network isn't jammed, technically it's a congestion which increases the feerate that you're seeing. Transactions are still being confirmed at the average time expected.

Whatever the use of ordinals, I do not believe it's worth the fees people are willing to pay for it and the ripple effect it has on other holders is very high. They have to use competitive fees if they want their transaction confirmed in priority time, or try accelerators.
