One method that blockchain analyzers use is to create the link between input and output addresses that are of the same type and consider it less likely for different types to be linked. Using a different type of address among the outputs could be an attempt at throwing chain analyzers off.
Of course on its own and on such a high profile transaction, it is a weird thing to do...

Usually predicting bitcoin in a year is a hard task, this year it is specifically tough because of the situation with the global economy. Bitcoin doesn't follow any other markets but it is definitely negatively affected by the economy specially by "recession". Everyone is already predicting more recession[1] on top of what we've seen so far and when it is accompanied by inflation, bitcoin can't have a bull market. So that option is out.

I personally don't see any more dumps coming anytime soon so that option is out too, but that's unless nothing big and negative takes place like another major exchange getting hacked or another country (like Taiwan) being invaded, etc.

For the time being, I'll continue taking advantage of the reverse bubble and continue accumulating.

Those who are brand new to this world must never start with any of the altcoins otherwise they will expose themselves to a whole lot of high risk situations that will result it lots of losses too. Just stick to bitcoin, learn how it works and how you should store bitcoin safely and how you should use it for transfer money.
Then if you liked this world you have to first study pump and dumps before getting started on altcoins!

When we talk about Qatar we should not forget that it is a tiny country that is surrounded on all sides (ie ground access) by Arab nations that have bad relationship with Qatar and it was not so long ago that they basically sanctioned Qatar and this country was seeing its end and would not have existed if it weren't for the only non-Arab country in their vicinity north of Persian Gulf called Iran.
So they need things like FIFA world cup or selling LNG to Europe so that they can ensure their long term survival by increasing their relations with the outside world in a place where they are still surrounded like before.
Even if the FIFA thing weren't profitable for them on paper, it had tremendous amount of benefits for Qatar for sure.

The recession is caused by the huge rise in energy prices which is only partially because of Russian sanctions. There are a lot of other reasons that led to these recession that includes the incompetence of governments in keeping the economy healthy specially after the pandemic started and they decided to print enormous amount of money out of thin air!

I don't think we can see any major war between military superpowers in the world. The only possibility is more proxy wars like Ukraine vs Russia, Taiwan vs China or Azerbaijan/Saudi vs Iran. And of course more cold wars.
Any direct war between these superpowers and NATO would escalate into a global nuclear war that could lead to extinction of human race.

I wish we see less speculators adopt bitcoin who want to make a quick (fiat) profit and get out. I wish to instead see more people adopt bitcoin who want financial sovereignty.

If you mean bitcoin's "inflation rate", I don't think halving is going to change anything about bitcoin to put it side by side with gold. They don't fall into the same category regarding age, spendability, adoption scale or even supply cap (gold isn't as limited as bitcoin).
If you mean the global inflation rate, your question makes more sense since inflation will always push people towards converting their fiat to something that is a better store of value. Both gold and bitcoin are good options for that.

With or without the inventor of Bitcoin, it can never be regulated because it goes against its principles of being decentralized. However, centralized services like exchanges will be built on top of bitcoin and will be regulated.

I don't think their position is going to change until mass adoption (which we aren't even close to).

The real question is if you want to commit a crime and evade taxes, of course the taxation itself depends on the country you live in since the laws about what is taxed and how depends a lot on your country. But also remember that the government doesn't tax your payments, they tax your business. In other words it doesn't matter how you receive payment (credit card, hard cash, bitcoin or monero) in the end you are still running a centralized service inside the regulations with a license (hopefully!).

This way of thinking is exactly why there are very few "millionaires" around. You are thinking of gaming a system (the faucet) that was not supposed to be used that way to earn peanuts! This is while there were (as there are today) lots of better ways to honestly earn a much larger amount of bitcoin. For example you could have turned your computer on and used your CPU to mine a single block to earn 50 bitcoins as the reward! Or even you could have spent $100 to buy 2000 bitcoins!

Well your in initial post is very misleading then, it sounds like you just jumped in following someone else without doing your own research.

Anybody should do some research on their own and see what bitcoin is, not just look at the charts and see the price going up and see some rich guy has bitcoin and follow them.
Bitcoin is the only decentralized currency in the world that can not be censored or sanctioned. You don't need a middleman to send, receive or hold bitcoin which means no one's hand is in your pocket when you use bitcoin but your own! It has a limited supply so we can say that bitcoin is the only existing money in the world too (everything else we have like dollar is currency not money).

If you "found" these files on the internet or worse paid for them, they are empty and fake.

99% of the Electrum history, it created a wallet file without any extensions and the content is stored simply as a human readable JSON file. .dat extension is one that bitcoin core and some other wallets use.
Specially if this is a wallet created in those two years, it is impossible to have a .dat extension.

The thing about smart phones is that they are designed to to be connected to some sort of network through different means, with or without SIM. A PC on the other hand is not designed that way and the steps you need to take to make it truly airgap are very simple and short. Your PC doesn't have an antenna by default, it doesn't have Bluetooth by default, or network card or a connected network cable, etc. all of which your phone already has.

The recent statements by the IMF managing director Georgieva paints a bad picture for the world economy in 2023. She claims one third of the world economy is facing recession. "tougher than the year we leave behind, because the three big economies – the US, EU and China – are all slowing down simultaneously," she said.

We should watch China closely, their economy is affected by the recent outbreak of Covid and it is expected to slow down if things get worse. The impact of that on the global economy is going to be massive specially since China is also in an economic war with the West.

Interestingly enough despite majority of economy experts claiming that US economy entered a recession in summer of 2022 and will face recession in 2023, she claims the opposite.

The biggest hit will be on regular people. Something like what happened to US, the 1% controls all the money in the world and middle class is eliminated while everyone falls to lower class. That 1% will remain "European" while their business (all their factories and production) takes place abroad like China and India, that way EU economy remains big while people get poorer.
Like iPhone being basically made in China while it is considered "American" and Apple counts as US GDP while regular Americans are out of jobs!

I covered the reason for Gold price rising. I can't comment on other assets in your area but S&P500 has been dumping, in fact over the past year it got dumped about 20% which is huge in such a heavily controlled market.

The thing about bitcoin is that the market can be easily manipulated and we've had a lot of negative news like FTX collapse that created fake fear and panic sell that crashed the market. But also bitcoin is affected by the world economy and as the economy crashes, more specifically has inflation and recession at the same time, bitcoin price has a hard time going up.

I don't think so.
This has been a trend not something that happened over night. The plans to make EU addicted to Russian gas has been going on for decades, the plans to invade Ukraine has also been going on for at least 10 years.

Same with Saudis, you have to look at the bigger picture. Saudi family did exactly what Russia is doing for the past 8 years but with the help of US. They invaded their neighbor, the poorest Arab country called Yemen to steal their vast energy sources and gain a strong geopolitical status. During during Trump administration the US military proved its inability to protect them against the country they've been invading. So when the invadees started retaliating and hit Saudi oil infrastructure, Saudi military bases and US military bases successfully the Saudi family realized US is too weak to ensure their future survival in the war ordered by US; so they slowly started changing their position and shifted toward East. This is why you see China in Saudi Arabia selling them crap while US complains and expresses "concerns" from afar without doing anything.

All these changes would have happened regardless of who the POTUS is and will continue after sleepy Joe goes away.

That's a weird poll, you should try to keep the number of options low whenever you want to ask a question like this (remember the multi-choice questions have only 4 answers as standard for a reason).

In any case, I think 2023 is going to be the most unpredictable year in bitcoin history. That's mainly because the world economy is unpredictable and many experts are already predicting a worse economy in 2023 and with the escalation of conflicts in different parts of the world (Yemen, Ukraine, Taiwan, etc.) things could get worse specially since the temperatures are dropping fast to unprecedented lows that EU and US were saying "would never happen"! while they have an energy crisis that has also affected their economy which in turn affects bitcoin price.

I chose the second option, because I think we can have a small rise (possibly breaking $20k) but I don't think we can see anything major yet. But 365 days is too long to predict at this time in this chaos.

That's true but you should remember that a project (old or new) doesn't have to be a scam for you to lose money. They simply are pump and dumps and you lose money when you don't accept that they are pump and dumps! For example the biggest altcoins in top 10 list are also pump and dumps since they have no other utility in real world. So when you don't know how to make profit from such schemes you always end up with your pants down during the dump and lose money specially if you are one of those people who decided to bag hold and hope for the recovery instead of cutting your losses and exiting.

To be fair bitcoin is not an asset and was never meant to be an asset. It is a currency that needs to become money hence this much volatility is not good for it at all. The only hope we have is for bitcoin to slowly decrease its volatility and big unpredictable swings, and since so far we have seen that we remain hopeful.

Hacks like this have never been because of a flaw in a cold storage setup but a flaw in the user himself.
In other words as long as a cold storage remains cold, it can not be hacked. For example you can never "hack" my paper wallet I have in my desk drawer but if you invade my home you can steal it now that I told you where it is (hypothetical scenario)!

I'll wait for more solid information on how this hack was taken place but if we assume this is real (not tax evasion ) then as @franky1 said it seems like he infected his wallet on his own, as a mistake.

To err is human!

Wrong.
There was a miner who has been mining in early days and at some point in 2011 they decided to consolidate all their block rewards into one output which they continued to mix/spend from over time. The only reason why that private key (of the already empty address) is known today is most probably because the real owner sold it later on to a shady person on the internet who wanted to pull some sort of scam or possibly used it to claim some shitcoin (like CLAM or something like that) and it got leaked.

At the end of the day an air-gap PC is the safest option compared to both phones and hardware wallets because it is physically disconnected from the rest of  the world whereas hardware wallets are not and phones are extremely hard to made truly air-gap.

The attacks you describe on PC are very complicated and more theoretical than practical specially since the attacker needs to be close to the PC and in some of these attacks they need physical access. Meanwhile there are other attack vectors on hardware wallets that are being connected to a system that could be infected. Granted they too are theoretical but there has been real cases in the past and when comparing it with your examples they are more serious.
