Also sounds like a kid in the back seat and the adult in the front.

Yes, the high probability is that the users' own errors. Getting professionals' opinions make newbies like me feel ease.

From quick google search, i found this https://www.reddit.com/r/BitcoinBeginners/comments/179epf6/reworked_the_utxosummary_and_it_although_it_makes/. But since it's created just 4 days ago, there's possibly OP and user on reddit are same person.

Edit: Yes, that's me, too. I also ask for feedback on Reddit and SN, but I feel like there aren't as much people who know as much about the technical side as there are here. The content really is mine.

He don't ask question, but ask for feedback about what he write.

Hey there, yes, i've wrote it all myself. I wanna know if there's anything inherently wrong in what I've written, as well as if there's anything to change or add in order to make it better understandable as a whole.

The theft of the Trezor hardware wallet is the most serious. Is it possible that there is a bad man inside the Trezor company who left a backdoor in the manufacturing process of a small number of wallets? And the genuine firmware of Trezor and Trezor Suite did not recognize it?

In terms of the "stolen" reviews you have found - do any of them actually provide any details? It is easy for a competitor to post fake reviews, and we've also seen countless users on this forum make posts blaming their hardware wallet for the funds being stolen, and it almost always turns out to be a mistake the user has made instead (such as storing their seed phrase in their emails). I wouldn't pick a Trezor device for many reasons, their anti-privacy and pro-censorship stance being the main one, but I also doubt any of these "stolen" reviews are true.

Am I the only one who uses coin control as the default option? Whenever I want to make a payment, I start by selecting the UTXOs I wish to spend. There are lots of reasons you should do this over automatic selection. Privacy is the biggest one, as has been discussed already. I want to spend specific UTXOs for specific things, and I definitely don't want my wallet automatically consolidating UTXOs I don't want spent together. I also don't want my wallet to consolidate UTXOs in a transaction where I am paying an above average fee for a faster confirmation - I'll consolidate any UTXOs in a combination I choose, at a fee I choose, and at a time I choose. If I select UTXOs manually, I can select one(s) to create an appropriately sized change output and not be left with dust, or spend the change somewhere else simultaneously, or create no change at all in the first place. It saves me money and fees in the long run, and protects my privacy while doing so. Why would you not use it?

I wouldn't even dream of using a wallet which does not offer manual coin control, and I'd quite like to have the option to turn off automatic coin selection altogether to eliminate the risk of making a mistake.

So if the user aren't aware of coin control and no nothing about Consolidating UTXOs, that will have no impact on the use and also this does not suggests a bad future for the bitcoin.

Market dominance of altcoins tends to increase during a bull run as both the old altcoins experience a surge, and new ones come to life and start rising again. This is a common market sentiment during a bull run, but it shouldn't be viewed as a consistent trend because the real market dominance of a particular coin can only be measured when the market is neutral, much like our current situation.

I wouldn’t be scared that the dominance of 2017 by Altcoins will happen again because people have seen their value bitcoin holds over them. In that 2017 year what the likes of ripple and Solana promised were fast transaction and people have found a way through that. So I don’t think many people will invest in new ICO projects agains like they did before

Please stop the bullshit comparisons equating Bitcoin with Shitcoin. From whatever aspect you judge, it will not be the same. be it the market cap of ETH, NFTs, etc that I don't want to know more about. Bitcoin's dominance remains a benchmark for why shitcoins can still have play in the market. There will be no signs of capitalist domination of Bitcoin. People will tend to take advantage of Shitcoin which is temporary in order to continue accumulating Bitcoin. Gradually

In 2017 we had ICO mania where everyone, even with an idea of an idea, created a token and pumped altcoin marketcap. in 2021 we had meme coin mania, when you dont even have to have an idea of an idea. You just need a name to lauch a token with milions in marketcap. In addition, a toxic strategy of pumping shsitcoins marketcap has become popular (creating tokens from 1% of units in circulation and the rest 99% is only used to increase the marketcap)

After the ICO mania, I thought that people had become wiser and knew not to invest money in such things. 2021 has proven to me that they are even stupider and more greedy.

That's right, it was due to the ICOs during that time and the craze was like how people have been into the NFTs. And it's like every week there's a new ICO project and investors are flocking into those projects and filling every crowd sale that they're getting. That was the time that when it's likely every project becomes successful every launch not until the bull run ended and 2018 came and still have tried but that's like the slow death of the ICO era. The same with the NFTs that have been the place of many scams, so do the ICOs were.

ICOs were kind of new and people were new to it and they pumped it and expecting ROI. Not knowing it is like pump and dump ponzi schemes. The price of the altcoins increased significantly. When the bear market came, the altcoins fell in price significantly and some were dead. Altcoins creation and pump makes them to compete with bitcoin and reduce bitcoin dominance.

An important factor was the number of new projects created at that time . At that time ( and earlier ) we had the ICO mania and also the separation of original protocol to branches . .    

Another factor is the issuance of coins , bitcoin has one of the lowest "inflations" as most of the supply was issued before 2017 while others continue to increase supply with insane rates

Hey thanks for the advice.

Does it work on a NUC PC?

It's been years since I had a box with graphics cards.

Other open-source hardware wallets (altcoin wallet, not bitcoin only) have few users and less attention, making them less secure.

1) I need a secure wallet to store altcoins, and I believe Trezor should be the best choice. It is the most famous among open-source wallets and has the least possibility of having a backdoor. Even for Trezor, the number of users is only slightly over a million (1M+, according to the official website).

Also if for whatever reason you want to use more than 3 signatures because maybe you want to stash more than 3 seed phrases in unique locations  then you can use a value of M that requires more than (emphasis on more than) 50% of the signatures, but allows for a certain of number of phrases to be lost - so somewhere around 60% - 75% of the phrases being required for recovery.
