We can say with certainty that the Samourai Wallet software you are using on your phone is closed source considering how their repository has not been updated for ~3 years despite them releasing a lot of newer versions (last release on appstore is on Oct 6, 2023).

The source code is hosted elsewhere (https://code.samourai.io/wallet/samourai-wallet-android) and is up to date. Although the github page (https://github.com/Samourai-Wallet/samourai-wallet-android) does not reflect this migration, unfortunately.
We are now one step closer to finding the reason for this odd behavior. The code has many "listeners" watching the clipboard for many different reasons in a a bunch of different places.

We may soon find out since more and more Western aid is going to the terrorist organization¹ helping them commit genocide in Gaza. Not to mention US itself is going to need a lot of aid defending against the barrage of attacks that has significantly increased ever since last night's terrorist attack on Gaza which was largest to this day. In other words the more they bomb Gaza, the more US bases are going to be bombed: https://www.talkimg.com/images/2023/10/28/T4YmT.jpeg

1. For nitpickers: in the last OIC meeting Israel is officially announced as a terrorist organization. Also if you have watched the latest series of speeches in United Nations, increasing number of countries are referring to Israel as a terrorist organization and/or their actions as terrorist attacks.

In a chaotic period as the World Order changes, all countries will suffer. The degree of it depends on a lot of things one of which is their resources (energy, food, minerals, ...) that can reduce the number of or severity of the issues they are going to face.

Another important thing that I always emphasize is having wise decision makers. People in key roles that can make the best decisions possible in order to get their country over this troubling times.
One of the best decisions that countries around the world have been making is creating these "altarnative" alliances, association, organization or whatever they may be referred to such as ASEAN, BRICS, SCO, etc.

On another news, this morning after having sustained more than a hundred casualties in the past week US CENTCOM decided to respond to one of the attacks by an airstrike on a storage facility in Syria.
As I had predicted, this response from US was met with an even heavier response by the Syrian resistance as instead of a small strike using shells or small rockets they used at least 10 ballistic missiles with heavy warheads to attack the US base close to the Al-Omar oil fields in Eastern Syria. The US casualties are expected to be very high.
Good news is that US seems to have gotten the message as they stopped showing any interest in responding to any of the attacks...

There are generally three main problems with ideas like this.
First is the centralization of such database that stores address+short_string duo which introduces a lot of problems from censorship to going down or giving false information.

Second is fake information that can be injected into the database without any control. Imagine we start this database and someone is faster than me and takes over my username (pooya87) and associates it with their own address. Now anybody who wants to pay me would go there and search my username and finds someone else's address instead of mine and I can't change that.
You may argue that they can contact me and verify it is my address but then why go through all the fuss in first place?

Finally it is the limited size. A bitcoin address is usually encoding 160 bits (20 bytes). The said database needs to contain easy to use words that are short (like pooya87 or 7 bytes) which means we are limiting the number of users this database can support. At some point we end up with long "words" (like the_real_pooya87_address_123) to be able to cover more and more addresses which at some point defeats the first purpose of it which was using short strings to represent addresses!
As a good example if you search my name (pooya) in forum's member list you can already see the problem as there are more than three dozen entries that are variation of my name.

Bonus issue: it encourages address reuse.

These aren't "onchain" analysis, they are "market" information. On-chain suggests stuff that happen on the blockchain or in the particular cryptocurrency network such as number of transactions. That does not really help with trading though since the data acquired on-chain does not directly correlate to what is happening in the market.

As for trading/investing the best source is still your own analysis of the market which you can only get by visiting the charts and using the centralized exchanges to see the live data. Otherwise some of your links like CMC are only good for finding where each shitcoin is traded not for analysis.

There are also some third party tools that can help with technical analysis like the tradingview.com website.

I suggest you take a look at the charts next time you wanted to start a topic like this and spend a moment contemplating it!
Last time price was $21k was about 7 months ago on 2023-03-13 with all the market manipulations and dump attempts only could bring it down to $25k (the new bottom and a strong support). Not to mention that today price is closer to $35k!

As for the past 5 years, the world is not the same though. A lot of things have changed. We've endured 2 recessions, one because of the pandemic and the other because of the proxy war between East and West that is still ongoing. That affects the global economy which in turn affects bitcoin market.

Tether is not backed by dollar, the centralized company that keeps "printing" more of it claims that it is backed by dollar 1:1 but so far there has not been any proof and many believe that they are lying.

Your comparison makes no sense either, Tether is a centralized shitcoin that should only be used by traders who want a quick escape from the market at times of high volatility or when they want to transfer funds between exchanges using a shitcoin without losing much in the transition. Otherwise it has no utilities.

I think it is still too soon for Bitcoin to play a significant role in the world.

On one hand we have this decentralized payment system that can not be censored which makes it an excellent choice for many free people around the world.
On another hand this currency has a very volatile price and it also hasn't reached mass adoption yet which makes getting paid or making payments in it complicated.

In other words it has both pros and cons and depending on the situation one could overshadow the other.

Case in point:
The cons in the case of the Palestinians and the Palestinian freedom fighters is their lack of access to technologies and even the internet. Specially the Palestinians that are kept in concentration camps or in Gaza which is known as the biggest prison in the world.
So for example even if you have all the money in the world but there is no food to purchase, it won't help. Obviously having bitcoin in this case won't help either specially since you'd have to convert it to fiat first then try to buy food that doesn't exist!

The slope of the chart which indicates the rate at which the national debt is increasing, is the scariest thing here. There doesn't seem to be any effort being made to "fix the economy" in the past 40 years, each government's solution is to print more money and the more they print the more they'll end up needing!

The even scarier part is the way the world is seeing US dollar these days as they are slowly dumping it. They are also dumping the US bonds (the debt they had bought) which is slowly but surely burying US economy...

The chances of an ETF being approved inside US is still minimal whereas there are a bunch of ETFs in a lot of other countries around the world already
In other words people are still making ETF much bigger than it really is and the hype is not even as big as some people speculate and even link it to the recent small rise. It is not the first time there is such hype and when something is "overused" it loses its hyped nature...

What you described here is not called "building a career", specially since it sounds like it was a one time thing. A single investment that also doesn't seem to have been with a solid plan, just a simple luck where price went up and produced some profit for the one time investor.
Even a career in this context would be a day trader who makes profit regularly from regularly trading bitcoin not a one time investment.

In any case, a solid career with bitcoin would be an actual business using bitcoin. For example the centralized exchanges, payment processors, online shops, etc. are good examples of other people who built an actual career with bitcoin.

It depends on the message you want to compute the hash for.
The smaller the size of the message the lower the number of blocks (internally used in SHA256) hence the faster it will compute. For example computing hash for 10 bytes is faster than 33 bytes and faster than 80 bytes and faster than 200 bytes.
It is slower if you want to compute double SHA256 hash.

In the context of bitcoin we almost always compute double SHA256.
33 bytes is size of majority of public keys that are hashed in the most common OP_HASH160 scripts.
80 byte is the header size that is hashed in mining and you can easily find stats for both CPUs and GPUs hashrates on the internet like [1].

Your biggest problem that blinds you to a lot of the facts of this world is your racist tendencies and your hatred of the civilized east. This is most clear in this post of yours. You support US while bashing China while they both are two sides of the same coin! A lot of what these two countries do are exactly the same too! Like (ab)using other countries to fulfill their own interests.

In fact in this world 99% of what you see as "alliance" is just a coalition. Like NATO

After reading this part I'm now very curious to know how you feel about altcoins. Because this types of strategies are excellent for the shitcoin market where there are flash pump and dumps. They also happen every day with dozens of shitcoins sometimes with massive pumps that can produce a nice revenue if you are willing to take the risks.

People shouldn't care what some random person says on the internet (or anywhere else for that matter) and most of them don't. Specially when it is people who want to be seen and gain some publicity in a certain community.

By the way this is not a "pump", it is a very small rise after breaking a resistance while price is still under the intrinsic value...

Israel is the oldest terrorist organization on the planet and the genocide of Palestinians by the hands of this organization have been going on for 75 years. So the headlines about it are bound to always be present in the mainstream media specially in countries that support this terrorist organization, in this case UK trying to cover up the genocide.

In short not unless it expands.

This time it is different because this time nobody in West Asia is tolerating Western support of this terrorist organization so they have been declaring war on US specially after POTUS visited the organization's headquarters and increased the supply of bombs used to kill Palestinian children.

Over the past two week all US military bases that are illegally occupying Iraq and Syria have been getting attacked regularly and US casualties are already in 3 digits.
Last night other groups in different countries joined in and declared that other US bases in West Asia such as in Saudi Arabia, UAE and Kuwait are legitimate targets as long as US continues supporting the Israeli terrorists. I haven't seen any news regarding attacks on these targets but if those bases start getting attacked it could significantly affect oil price which in turn affects the inflation.

Additionally these attacks have been "light" so far, using loitering munitions, rockets and shells taking small number of casualties from US military. More importantly US CENTCOM has not dared respond to any of these attacks.
If CENTCOM decides to retaliate against any of them, the attacks will change in nature and become "heavier" using missiles with heavier warheads and deadlier loitering munitions and using much larger number. Which would also expand the conflict to the seas, namely Red Sea (Suez Canal, Bab al-Mandab Strait), Persian Gulf (Strait of Hurmuz), etc. that would not only affect oil and gas supply of the entire world but also affects the international trade by shutting down the trade route through Suez Canal. This can cause hyper inflation very quickly.

The only thing a 100 char long password used for BIP38 does for you is to make your work entering it in the future for decryption a nightmare, more so when it is random!

It does not provide you with the security you think it does because in BIP38 algorithm the password is fed into scrypt KDF to derive a 32 byte key which means when you use a bigger than 32 byte password to derive a 32 byte key, your security still depends on the 32 byte size not the much bigger password (eg. 100 byte).

Theoretically to brute force your password, one would just skip the first step (ie to derive a key using scrypt that needs to iterate 100 bytes) and just brute forces the 32 byte derived key.
Realistically since 32 bytes is 256 bit and impossible to brute force, this is impossible to pull off.

This part may be a little tricky specially if the "company" behind the wallet is trying to fool people. There are a couple of ways closed source wallets use to pretend they are open source.
- One way is to open up a GitHub account and put some code on there. It could be an older version of the wallet that is no longer updated or it usually is only part of the wallet code like the backend instead of the entire thing. People checking this on GitHub would think it is 100% open source when it is not true.
- Another way is to publish the entire code but the code has nothing to do with the binaries they release. For example there are some wallets specially the mobile wallets that have a published source code but the code is not updated with their releases! In other words they release a new version but when you check their code, you see no activity!

This is why having reproducible builds is important.

Privacy always comes at a cost.
When you use Tor, apart from the slower communication speed you will also consume more traffic which could be a small concern for those with a capped network. Each time you use Tor, apart from the Tor relay information you have to download, all your communication is also encrypted which adds an extra overhead.

The biggest thing to look for in National Debt isn't only the size of the debt (or even the ratio with GDP). The important thing to look for is where the money is going!
You see in some cases printing money out of thin air is not the worst thing but only as long as that money is entering a healthy economy and goes into production. But when the money is being printed to cover some deficit, pay for extra costs that never existed before (like starting a couple of very costly wars), etc. that is when it becomes problematic because the government would be increasing liquidity WITHOUT increasing the size of the economy. That means higher inflation.

This is exactly why US has a very high interest rate these days. All the money they've been printing has been increasing the inflation and to battle that they are desperately manipulating the interest rates which is not working as well as it should while causing recession at the same time...
