The only reason for Elon Musk's actions is trying to remain in the spotlight and then use that publicity to make a lot of money. Take a look at how he pumped and dumped a shitcoin called DOGE. So essentially whenever you create a topic about him or there is a "discussion" involving him and another public figure, you are all playing into his hand and fueling his future scams.

Existing Shitcoins should be already dead by 2024 or replaced by other newer shitcoins that aren't as pumped considering that has always been a lot easier to pump new shitcoins and those that already have a very low price not the high price overpumped ones.
ETH price should be around 0.0005BTC, Cardano less than 500 satoshi and Binance should go in the same list as its predecessors and its centralized token BNB should be dead.

That's assuming that the demand (buying pressure in opposite of sell pressure) is not going up faster. Considering that bitcoin adoption is still in its very early stages and the demand is increasing, we can safely say that this assumption is not true.

Rate of bitcoin creation is obvious (it is currently 6.25 per block).
Rate of bitcoin being lost is not possible to measure or even estimate. The ONLY thing we have is the provably unspendable outputs that are mostly OP_RETURN outputs. Coins send to these scripts are lost forever.
Even though blockchair explorer has become very terrible after the recent change but you still can find them here.
You may need to change the value and set it to at least 1 satoshi yourself, the link doesn't seem to be recognized

You can see that there are coins that are being burnt but the amount per month is usually less than a 1000 satoshi. For example blockchain doesn't seem to even find any for May and June.

My opinion is that you should try to make an honest living instead of trying to rob others. I don't think stealing is legal anywhere in the world either.

Apart from that others already mentioned that it is not possible to find a private key that was used before at random. The code is written in such a stupid way too which is why it can only check 26k keys/sec instead of something like 100 million key/sec which is understandable because a developer who has a better understanding of how to write code and understanding of basic cryptography knows making such a tool is a complete waste of time so only newbies with no understanding of anything do it...

It doesn't discard the entropy it increments it[1] and you don't lose entropy by incrementing it. It is basically the same concept as vanity address generators, they too start from a random entropy then increment it until they reach the desired address.

First of all you are thinking in reverse, we aren't selecting words out of a word list. We are encoding a stream of random bits to human readable words. Secondly what we generate as an "entropy" in programming is actually not a stream of bits but a stream of octets or bytes. So we can't have 132 bits, but 128 or 136 bits. Even Electrum mnemonics are actually generating 136 bits then reducing it to 132 bits. And finally that wasn't even the part I was "nitpicking" it was the wording in the part I quoted which could be interpreted as a 128 (or 132) bit entropy is "far less secure" than a private key which would be a false interpretation because it provides the same security as I explained above.

Again you are thinking in reverse. We are not selecting words, we are just encoding an entropy and the equal length entropies are the same thing no matter the encoding (Base16, Base64, PGP words, BIP39 words, ...).

Bitcoin "wallets" are not like bank accounts to have a location in a country, unless you are not talking about a wallet and instead an account (sometimes referred to as custodial wallets) in which case you are still the owner of those bitcoins in the eyes of the "tax man" and same tax laws apply and you should consult an expert to know the details in your jurisdiction.

I'm curious how does one lose bitcoin in an accident?

I agree that halving is not as significant an event that some people make it to be but it is still a very significant event that affects price too. Of course there has always been two types of effects, the short term which only happens roughly 2 months prior to the actual date where the market is over hyped and a small bubble shapes which will pop as the date is reached.
And the longer term effect which is directly related to the new supply generation being cut by half. Even though bitcoin has a max supply we are still "printing" more bitcoin every day, these are coins that enter circulation and are mostly sold by miners to pay their bills. Consequently there has to be less sell pressure when we "print" about 900BTC per day in this period versus when we were printing 1800BTC per day in previous period.

Of course I should add that I believe that the main reason why price keeps rising is because of "demand" (not just the supply) which is both more people buying bitcoin and people who already had bitcoin buying more of it.

There are only two possible scenarios in my opinion which I've been saying from way before price even broke previous ATH at $20k.
1. We continue the same increasingly bigger bubble 4-year cycle and by the end of this year price reaches $400k+
Considering that the past 3 years starting from the bubble burst in first quarter of 2018 (that means entire 2018, 2019 and 2020) were pretty much the same as the previous cycle (that means 2014, 2015 and 2016) and the start of 2021 is also similar to start of 2017 with breaking previous ATH ($1200 versus $20000) with high difficulty, multiple big drops and a lot of drama at the middle of the year despite price being a lot higher than previous ATH (that is $3k of 2017 versus $30k of 2021). I would say that we are on track so far and I don't still see any reason why this trend should be broken.

2. We finally break the 4-year cycle and put an end to it. Which means from now on we can no longer predict how the market goes, there will no longer be a year long bear market when the big bubble bursts. There won't be long accumulations at a very low price. There could be short big rises and short small corrections from now on.
In this case it is hard to predict things until the new trends start shaping up. But it is quite possible to end the year with a new but much lower ATH, maybe at $100k this time.

By the way here is a comparison of the two "cycles" and this time the cycle is happening a couple of months earlier but you can clearly see that the pattern has been the same:

Here is two links that can help:
https://en.bitcoin.it/wiki/Deterministic_wallet
https://www.oreilly.com/library/view/mastering-bitcoin/9781491902639/ch04.html#hd_wallets

In simple terms think of it as a function that takes an input and returns the same result if the input is the same. Like in math f(x)=x+7 if you enter x=1 you will always get the same result but if you enter x=2 you will get an entirely different result. Of course the algorithm to derive keys is a lot more complicated and works with much bigger values (an initial entropy of at least 128-bits).

edit:
I thought this wallet was the one supporting Electrum seeds, or am I thinking of another wallet?

I'm not sure which part you are misunderstanding but let me explain how things work.

The "recovery phrase" also known as seed phrase is used by HD wallets to derive your keys. Your wallet is going to store these keys. If you generate the seed phrase on Electrum then import the same thing in another wallet that supports Electrum algorithm, you WILL get the same keys (so same addresses) from it.
You can do this offline, online, on another machine, using another wallet, etc. You should always get the same set of keys. That is the whole point of Hierarchical Deterministic wallets.

Keep in mind that it is not safe to re-use the same seed phrase on more than one device using different wallets. Try to generate a new seed phrase on the other wallet (Mycelium), this way you don't risk losing your funds in case there were any bugs in the other wallet that could reveal your keys.

RFC6979 is more complicated than just simple hash of message+private key though. It is basically a complex key derivation function that can deterministically derive the ephemeral key (k) needed for signing based on the curve you are using, that means the k it produces is always in range and if not it will continue computing in a loop until it is.

To be clear a 12-word mnemonic using BIP39 algorithm has 128 bits of entropy, the rest is the checksum.
Also a n-bit long entropy provides n bits of security while a n-bit long elliptic curve key provides n/2 bits of security that is why the BIP39 entropy size starts at 128 which is the same security level as the bitcoin 256-bit private keys.

Being volatile is not the same as being pump and dump. A pump and dump coin is one that has no reason whatsoever to go up and then the drop of it is guaranteed. Take any altcoin price over the years, for example a coin that goes from 10 satoshi to 1000 satoshi (aka pumped), it will eventually come down back to 10 satoshi even if it takes a long time because it was initially "pumped".

What bitcoin has is natural rises due to real adoption not someone fake pumping it, that is why its price never comes down in the long run. Last year price was below $10k and now it is $above $30k which is a 3x rise. In short term because the bitcoin market is small and is filled with newbies that never had any entry barrier, the price can make big moves in short term.
Why choose #6? Take #2. It used to be pumped and worth 0.15BTC and now it is struggling to keep 0.05BTC even though they pumped it hard in May to only reach 0.08BTC.

If seed phrases were sent to servers then Electrum would have been considered an insecure wallet software and nobody would have ever recommended it. As @hosseinimr93 said the seed generation, validation and key derivation all happen on client side (on your computer) and the only thing you send to Electrum nodes is your address which is "public" to get your transaction history.
The point of using portable versions is to have a software that is ready to run without needing any dependencies. This way you won't need to download any packages or worry about missing components needing to be downloaded. Other than that the software is the same and security of it depends on the system you are using it on.

That's because bitcoin market and its movements are more natural while Dogecoin and other altcoin's movements are based on pump and dumps and it is very easy to pump shitcoins. You are just choosing a random shitcoin (Doge) simply because it was in the news and pumped by a so called "celebrity" otherwise there are other similar shitcoins that get pumped a lot more and are much more profitable than Dogecoin. Two examples of these shitcoins from the past 24 hours are CELO and NANO they got pumped 25% and 21% respectively. And these are among "bigger" shitcoins, there are smaller shitcoins that get pumped A LOT more. For example DVPN got pumped 134%, BTRL got pumped 3173% and so on!

Another difference is that when bitcoin goes up (in long run) it will remain up but shitcoins go up (aka pump) then eventually they come down (aka get dumped).

To be fair people don't have to buy "every" dip and I dare say they can't. How much "extra money" do people have anyways? Keep in mind that most people don't day-trade so they don't always have the cash.
Usually you'll take advantage of a couple of big dips and make your purchase before running out of money to put into bitcoin and should be happy about it even if "better" opportunities appear afterwards. With that said anything from $30k to $40k is THE dip to buy in.

Nice joke bro.
He came into popularity back in 2017 and his popularity vanished just as fast it came when he started scamming people and when ICO craze ended. He practically disappeared from "crypto world" when the 2018 bear market started.

A better question is whether he owned any cryptocurrencies at all. As I remember it back in 2017 he was getting paid mainly USD to advertise ICO scams on his twitter and when he was pump and dumping shitcoins he would have cashed out fiat in the end.
He also didn't believe in or care about bitcoin as it is evident from his actions, he was in "crypto world" to make as much money as he could quickly.

I don't want to speak ill of the dead but we will remember him as a scammer.

They are called Casascius "physical bitcoin"[1] not tokens. They are meant to be used as collectible not what you redeem (that is revealing their private key and spending the coins in that key). Usually these physical items are traded as collectibles at a slightly higher value than the coins they contain. You should be able to find some topics in collectibles board[2].
But if you want to redeem these coins you have to basically "destroy" the item by removing the private key protection and revealing it. The keys used by these coins is known as mini private key[3] which is a special format that only a handful of tools would support. One good wallet to use is Electrum[4], you can directly import the mini-key in Electrum[5] and be able to spend the balance.
