I even saw Bitcoin dominance going below 40% to around 37% on Coingecko website but now it started to go back up with currently holding around 44.7% and growing.

Not sure what will happen in future but we are never going to see mythical flippening some people would like to see and we are still holding the path for Bitcoin stock-to-flow model made by PlanB.
Sure, we can go even lower due to fud from all sources like Elon, China ban and new regulations, but look long term and remember that fiat printing machines are running non-stop, and prices for food and everything else are rising.

I am really not surprised anymore after year 2020/201 how people can be ultra stupid, not using their brain and not doing any research before trusting anything they hear or read in email or mainstream news.
One guy even commented that his father was very worried about this sextortion email he received, and than his son had to remind him that they don't even have webcam on their computer.
Fear Sells the best, just don't buy it.

Electrum is open source wallet designed for holding and transacting with your Bitcoins, so there is no service in this case.
People donate to Electrum developers because they like it and project stay updated for years.

Trust wallet is sponsored by Binance exchange and I don't think they are open source so you need to trust their code.
Similar like Atomic, they earn fees from people who are exchanging and staking some altcoins.

There is no monetary gain from using any of this wallets, I hear some people are complaining about Blockchain.com wallet and I see no reason of using web wallet like this.
If their website shuts down or if you lose their login password you can potentially lose all your coins.

It depends what wallets you are using but if you want to be totally sure I would first delete everything from devices and than smash it with hammer or burn them in microwave.

Trezor have Wipe memory option and I think Legder have something similar, but there can always be some leftovers in memory or in secure elements so I would not take the risk of trusting microchips when some future exploit could extract all information.

Ne propada ti ništa.
Skoro svi hardverski novčanici koriste isti standard i samo moraš znati da li imaju drugačiji derivation path, koji se onda unese ručno.
Isto tako moraš znati tip adrese koju si koristio za Bitcoin, npr. Legacy adresa počinje sa 1, P2SH koja počinje sa 3 ili bech32 i taproot koje počinju sa bc1.

Coins are not really stored either on their device or on their website but device is only holding seed phrases.
I recommend people to only use open source wallets like Electrum, and Trezor, Coldcard or Bitbox are very good open source hardware wallets and you can check this List of all Open Source Hardware Wallets.
Ledger wallet is also popular but keep in mind that it is closed source device and they had multiple customer information leaks so far.

Where is the proof or some source link showing that someone actually send total of 4000 Bitcoin for this stupid extortion emails?
I also received same sextortion emails several times before and I don't even have camera connected to my computer.

That address that is inactive since 2018, it had total of 14 transaction and it received ‎0.93 BTC and not 4000 BTC like you say.

It looks to me that OP is trying to promote his own btctester bitcoin analytics and forensics website with sensational and fake news like this, and that is not a good way to promote anything. 

You are mixing many things up, paper wallets have nothing to do with exchange accounts that usually need your email address and password, but you don't have any control of coins in your account.
Access to your exchange account should be possible from anywhere in the world if you have your login details unless some country is in some restricted region,
but they can always lock your account and freeze your coins or withdrawals like we see happening in Binance and other exchanges.

There is no special device that can scan your smartphone and laptop if they are encrypted and protected with strong passwords, but if they want governments can always extort and blackmail you to give them access or go to jail.
Backdoors for devices are also possible but why should they waste time on this when they can break people much easier with old fashioned mafia way, and they are also working on bounties for cracking hardware wallets.

I don't like this idea of multi tiers, and Bitcoin mining devices are energy agnostics like any other electric devices, that means they can use electricity from whatever source, coal, hydro, nuclear or even poo if someone invents such device that transforms humans feces into energy.
People will again send and mix coins from all pools, call them green or dirty and this efforts to divide Bitcoin in tiers will be futile in the end, like it happened with Marathon opac compliant mining pool.

China is banning Bitcoin every year so I think it would be a good idea to have special Bitcoin Ban day we can all mark on our calendars and celebrate annually.
Look at it from positive side, if they ban and restrict Bitcoin mining that means that pools from other countries will have bigger share and there will be no more fake news how China controls Bitcoin.
Bitcoin is like a living organism and it adapts to whatever conditions are in the world with regulations and everything else, but I think Chinese will just move everything underground and continue their business as usual.

Privacy is very important and one of the basic human rights and Bitcoin must have better privacy in future maybe with some second layer, sidechain or code upgrade, maybe even lightning network can be used for privacy.

I am always looking for interesting new projects and I found something called zCash Sidechain using BIP300, zSide and Melt/Cast for making fully anonymous transaction.

One more interesting project I am currently testing is Mercury wallet that is still in early development and it is using something called coinswaps on layer two statechain that enables transfering of private keys without any on-chain transactions.

This is possible only if you import your seed words from first ledger device to second ledger device, there will be no transaction and you will have full control on both devices.
Keep in mind that coins are always on blockchain and not actually on hardware devices but importing seed words on multiple devices you can lose all your coins, and you are reducing your security,
so do this only if you are the owner of both devices.
All transactions for coins like Bitcoin are public and everyone can see them, but using coinjoins with Wasabi wallet or bitcoin mixers like Chipmixer will increase your privacy a lot, but there will still be some transaction history for receiving address.

Većina hardverskih novčanika koristi BIP39 format tako da su kompatibilni ali treba obratiti pažnju i na Derivation Paths koji se mogu razlikovati kod nekog od njih, posebno za druge manje poznate coine koji nisu Bitcoin.
To važi ne samo za hardverske nego i za sve ostale softverske novčanike, Trezor, Ledger i Coldcard su sigurno kompatibilni za Bitcoin a možeš pogledati i ovu stranicu walletsrecovery:

I ja mogu sa 100% sigurnosti reći da dolazi smrt dolara koji je mnogo stariji od Bitcoina, a već nam spremaju horor vladine carbon digitalne Govcoin valute i social score kao u Kini samo još gore od toga.

I am not pro researcher or writer but use your own head and think for a minute.
According to some stats just in year 2020 global electric car sale was around 10,800,000 and they all spend electricity for charging all the time, while zero electricity is spent for gasoline cars.
Just one average electric car spends 33 kWh per 100 miles, now if you multiple that with millions and billions of cars you will get some interesting numbers.
Much more electricity is spent on production of Lithium batteries, and even simple stand-by electronics we all use at our homes are spending much more electricity than Bitcoin, and that is the fact.
Looks like you love proof so here is some data comparison that you won't hear from Bill Gates and clowns like him, always-on electric devices in America are spending 1,375 TWh/yr,
that is 12 times more compared with Bitcoin network estimated 113.89 TWh/yr.
I think every house have one or more cars in modern western world, now imagine if every car will be electric by 2030... and they all spend electricity all the time, numbers go up so easy.

New hardware wallet model CoolWallet Pro introduced new Secure Element J3R110 that has higher evaluation assurance level EAL6+ compared with their older model CoolWallet S, and this chip is often used in smart cards.
I don't see any big improvements or changes and this wallet still remains closed source, so I would look for other alternatives.

There has been many changes in Bitcoin code and Taproot will be next one, but majority needs to agree that change is good and not just two random rich guys.

It's not as easy as just increasing block size that would not fix anything long term and would result in more forked coins.
Just look what happened with BCH joined project of CSW Faketoshi and RogerVer aka MemoryDealers, that later split into one more fake coin BSV, and after that Amaury Sachet forked his own coin BCHA.
That is the circus show you will get when someone decides to just increase block size and create ''better'' Bitcoin vision.

Smart contracts are so smart that stupid developers are making so much bugs and every day we hear news of some new exploits resulted in losing of millions.
I don't know what is worse smart contracts or smart phones, seems to me that both of them are making people more stupid, but gold medal goes to smart contracts.
Bitcoin should never have smart contracts, but scripts are still possible and they will be used much more in near future.

C'mon man  
This is just crazy thinking and you obviously watch to much CNN and mainstream media if you really believe that Bitcoin mining will ever consume 50% of world electricity.

Sve radi bez problema i ne samo kod nas nego P2P najviše radi u ostalim zemljama koje su zabranile crypto,
a ne moraš se nalaziti sa nepoznatima ako si paranoičan i imaš druge opcije uplate na račun, Advcash, Paypal, Monegram, Skrill...
Ili se nadješ sa nekim u kafiću sa puno ljudi i povedeš sa sobom nekog prijatelja, sigurno nećeš ići sam u neku mračnu uličicu, podrum ili ispod mosta za tako nešto

Nije nikakva tajna da stalno pratim novosti za sve hardverske novčanike, a moguće je da tih Wookong modela više nema u prodaji pa ih možda možeš prebaciti u sekciju Defunct/nisu u funkciji/ne mogu se kupiti.
Ima tu još novčanika sa liste koji je više ne mogu kupiti ili su mrtvi kao npr. FLX One, KeyWallet Classic i Pro, Xzen, Littleshell, Esecubit, Coinlet, Case, Secalot i KeyFort K300.
Na prvoj stranici nedostaju i fotogrtafije za FuzeW i Lattice1.

Ne igrajte se sa tim glupostima i lažno anonimnim karticama kad imate više opcija kao BitcoinStore i P2P stranice za cash trading bez kyc verifikacije kao npr:

- LocalCryptos je non-custodial i ima podršku za BTC, ETH, LTC i Dash, naknade su od 0.25% do 0.75% i možete postaviti svoje ponude.
- HodlHodl samo za Bitcoin i sličan je kao LocalCryptos.
- LocalCoinSwap ima podršku za Bitcoin, Ethereum, Dash, Polkadot, Kusama, USDT, USDC, Dai, a naknada je 1% za ponudu.
- AgoraDesk trenutno nemaju ponuda za HR ali sami možete postaviti svoju ponudu za BTC i XMR.
- Bisq - mora se imati Bitcoin sigurnosni depozit, i nisam siguran koliko pounda ima za HR.
