It is a lot of effort if it is pointless.
Twitter is not a marketplace so adding a cryptocurrency to the platform would only be for tipping and we already know that tipping with shitcoins such as Dogecoin is not going to do much for its utility or popularity and it won't last long. A lot of other platforms have tested this, we had it on Reddit for example and tipping was heated for some time before it died for good.

In other words adding Doge to Twitter means adding a "game" to an otherwise serious platform which they know is going to die soon and they would have to remove it then. And for what? A short lived pump! There are other easier ways to pump a shitcoin that doesn't take this much effort.

Bitcoin is not changing anything in any of the cryptography algorithms it is using and there is no proposals.
Ethereum is also not changing the cryptography, it is centralizing itself more by changing its mining algorithm to something that would cost nothing but gives profit to the owners of the 72 million premined ether namely Vitalik et al.
I'm also not clicking that link but it is saying "RSA encryption" which is not used in either bitcoin or ethereum!

If those wallet files were real, they would have never sold them.

Every single case you see on the internet is either malware that is intended to steal your coins or is simply an empty wallet file manually modified to look like it contains keys to popular addresses with large balances.

It looks more like an effort to address all the recent breaches in National Security, Department of Defense and other top secret intelligence that has been hacked over the past couple of years which are only increasing in number and frequency. Possibly the 2 guys they caught recently who had infiltrated Department of Homeland Security for years without a problem was the last straw LOL
I don't see any relationship with bitcoin or cryptocurrencies though.

You are showing a middle finger to bitcoin's fungibility as a privacy providing tool and are censoring people selectively and you are saying there is no dishonesty there just because you announced what you were doing? What other choice you had? You couldn't hide the censorship, people would have said something on the internet about how their coins are being blocked by your tool.

You can't seriously claim having any shred of honesty here. Not to mention that whoever is pressuring you to enforce the censorship is surely pressuring you to do a lot more.

You can easily keep the 42 million hashes in memory and the memory comparison is not expensive at all, it takes a second to go through the list. Not to mention that the search can be optimized as it was mentioned earlier. You just sort it and then decide what part of the array you should look into and decrease the comparisons from 42 million to around 100 or something.

It won't matter how much you speed up your comparison process because that is not the bottleneck. The actual bottleneck that makes finding an address collision is the fact that you have to compute the very expensive private key to public key and then perform another expensive hash (SHA256) followed by another expensive hash (RIPEMD160). Expensive in this context is in comparison to the hash-comparing process (your binary search).

Your arguments are still flawed because you are looking at the empty part of the glass and it still doesn't explain why they stopped accepting free money. You are saying yourself that the number of people who use bitcoin as payment is NOT zero which means there are people who would have donated to Wikipedia using bitcoin (somewhere around $100k to $150k free money if my calculations were correct).

Lets assume the 2/3 is correct and the blog post wasn't some false blockchain analysis like they always are. And lets assume there were 9 million bitcoin users that means 3 million bitcoin users use bitcoin for payment and when the adoption grows to 18 million that means 6 million bitcoin users use it for payment.
The fact that number of speculators is also increasing is not going to change the fact that number of payments is also increasing.
(some sources say it is close to 100 million which would make it 33 million user who would pay using bitcoin).

It's the same with El Salvador, it doesn't matter if majority of people were only interested in that $30 airdrop. What matters is that many people who weren't using bitcoin (even if it's just 1%) before it became legal tender are now using bitcoin.

You keep saying problem but the problem that bitcoin market is facing is not that it is not reaching new ATH, the biggest problem (which happens to be a very new issue) is that a lot of people suddenly decided that after 13 years bitcoin should start following the US stock market movements for no reason! Since US stock market is having a lot of dumps, consequently they start dumping bitcoin too hence preventing the rise from happening.

There is no mining defined in PoS.
In fact PoS is a centralization scheme that open up room for a lot of attacks against the decentralization and security of the coins that use this algorithm. One of the simplest that the governments love would be to crack down on a centralized exchange like Binance that hold a large number of a PoS shitcoin or the foundation of that centralized PoS shitcoin like ETH 2.0 and by taking those coins they can have full control over that shitcoin's blockchain.
This is impossible in PoW.

I wouldn't call it "staking" because it is also misleading since we have staking shitcoins (eg. PoS coins). It is more like an investment and I personally hate centralized exchanges and any kind of options they provide. It is just too risky, they can be hacked or shut down at any moment. Not to mention that historically CEX has had a short life when they remain on top and when they fall, all their options fall in profitability too.

On the other hand, the rest of businesses that accept investments (like gambling sites) are better in my opinion. Like freebitco.in specially since it is old and the profit is reasonable not something crazy big! There is also the benefit of lack of KYC which is going to always exist in CEX.

One of the biggest problems that newcomers have is that they don't spend any time learning the basics and I blame the shitcoin advertisers as they are brainwashing newbies into rushing to buy their shitcoin.
In this case, bitcoin doesn't have anything called "gas" which is a shitcoin concept. Bitcoin has transaction fees and they are paid based on the size of transactions in byte not the amount of bitcoin you are transferring.

The gas or the fee in these shitcoins are not high because of their price! It is high because they have horrible scaling issues that are hundreds of times worse than what you see in bitcoin which is why fees on a shitcoin like ethereum went so much higher than fees on bitcoin!

Even though you are right about the "bitcoin is expensive" FUD that has plagued the community for some time but this is still another problem with newcomers. Bitcoin is not supposed to give you profit. It is just not designed for that purpose and you shouldn't think about how much money you are going to make if you bought bitcoin today!

RIPEMD160 still provides the same 160-bit security due to its size and the algorithm.
The reason why the bigger versions (256 and 320 bit alternatives) produce smaller security is because they are not different algorithms, instead they just extend the hash of the 128-bit and 160-bit algorithms.

Free speech, just like democracy, is an illusion created by modern dictatorships to keep people in line. You only have it as long as you are not stepping on the toes of those who are in power. For example you can practice your free speech all you want when it comes to silly things like changing the fundamentals of English language but if you dare speak out of terms against policies and you will be dealt with.
Your friends in the north showed how much free speech they had when they cracked down on truckers and anybody who showed slightest amount of support for them!

No altcoin has ever produced nearly as much profit as bitcoin has over the long term. If they had their prices should have been more than bitcoin instead of being far below it. The biggest pumped shitcoin called ether still has a price that is 0.07 bitcoin.

In short term on the other hand, shitcoins can get pumped significantly. You can see a 1000% pump in 2 hours very easily but that would also be followed by an equally devastating dump.

Of course there can be but the problem is that to this day nobody has made any effort in creating one. Every single one of the tens of thousands of altcoins that we have seen so far were poor copies of bitcoin in one way or another with a handful of exceptions that suffer from other issues. But majority of them were created for short term profitability not as a new technology.

Google trends has never been an indicator of anything and almost all the conclusions made based on it have been wrong. For example take the search term "bitcoin", you are are only considering it in English not in other languages but make your conclusion globally; whereas people in different languages would be mostly searching it in their own language. For example the following shows how people would search about bitcoin in Farsi:
https://trends.google.com/trends/explore?date=now%207-d&q=%D8%A8%DB%8C%D8%AA%20%DA%A9%D9%88%DB%8C%D9%86
Or in China the words seem to be "比特币".

Unfortunately Google doesn't give you number of searches but only a percentage wise comparison so you can't even compare the different terms with each other.

So what's the point of all this effort that you put into this work? Is it to get lucky and earn some free money if someone was dumb enough to actually hold any coins in any of these keys?
I assure you that you would have earned a lot more money if you had spent your time more constructively.

The final experience you are going to have with bitcoin depends on how you view bitcoin.

If you think of bitcoin as a get rich quick scheme and then buy it emotionally and sell it emotionally, it is obvious that your irrational behavior will leave you with a negative experience in the end. In other words losing money is guaranteed for you whether you find bitcoin when it is worth $1 or $1 million.

But if you think of bitcoin as it was meant to, meaning as a currency, then you soon realize that the price is not the only thing that matters specially the short term fluctuations. Then you start having a more positive experience.

I don't think Satoshi (who made this decision) has ever answered this question, so we have to guess.

What HASH160 seems to prevent is second pre-image attacks. It also is both shorter (compared to SHA256) and provides the at least 128-bits of security that exists everywhere else in Bitcoin.

I think your list has to stick to popular and reviewed wallets that support Taproot instead of any random low quality ones that add the support. Or at least clarify that your list is not an endorsement of the said wallets. For example I took a quick look at Nunchuk and their repository doesn't look very active after 2 years and the wallet is definitely not popular. I don't think anybody has ever reviewed this.
