You would be surprised to find out what people are spending their money on these days.
She or He is selling ''legitimate product'' whatever that means 

Well done PowerGlove!
You should receive special developer title in your profile if this gets approved.
I hope QR code will be only optional and not mandatory like on some websites, but this preview looks great.

Is there any chance of something getting messed up with code in future that could permanently disable login to bitcointalk forum?
To prevent this potential problem there must be some fallback option for that, without reducing security.
We also don't want hacker abusing this to somehow attack bitcointalk.

Pa nisu mene zvali da se preselim u Dubai, a ako je buduća  žena bogata veće su šanse za financijski profit (ako se dobro pokažeš).

Šalu na stranu, ti si definitivno najveće otkriće našeg lokalnog boarda ove godine, a ja ponekad mogu imati čudan smisao za humor, ali želim ti sve najbolje

Thank you for your kind words SirJohnVonSlotty.

It was a real pleasure working with you in last few months, and I hope to see you back with some new interesting project soon.

This looks like Ballet wallet to me  and without checking I bet this product is coming from China (even if they are based in Spain).
Anyone can create a wallet-like product today and post it on Amazon and Ebay, but they won't have much customers.
I saw many weird hardware wallets and we are following all of them in our local board, it's a wild wild west space and I am going to add this one also

Magic? Many kickstarter projects never deliver even if they have good idea, but I don't think Material Bitcoin was ever any good  

I am not going to add any custodial wallets in my list, and in general I don't support anything BitGo is doing.
If I remember correctly there was some big hack and vulnerability discovered recently with BitGo... but I stand by saying not my keys = not my coins.

This looks interesting, I bookmarked it and I will check it out and investigate more in next few days.

Not  true, and I didn't notice anyone doing that here.
I had no affiliation with Whirlwind whatsoever and I criticized your behavior, but I also stated that whirlwind email support could act better in situations like this.
However, you can't expect from small team to reply to your every message, and by writing a bunch of posts in forum you are just digging your hole deeper, people just won't take you seriously enough.
You can continue doing what you want, but you won't help your situation at all by doing this.

What does background check for incoming coins mean exactly?
Are you going to reject coins from some sources and return them to sender or not?
Trusting private investors and worldwide centralized exchanges is not good, and based on your website you are doing that and working with them.

I don't believe in complete anonymity with Bitcoin, and I wouldn't pay extra high fees using new websites that promises to provide service like this.
After performing some testing I could say more, but I don't see anything special that stands out from all other Bitcoin mixers available now.

Self-moderated topics are great and beneficial but they can be like double-edged sword sometimes.
History showed that scammers in forum often used them to trick other people and to delete unwanted comments they don't like.
I am creating self-moderated topics only when I expect more spam comments and whenI don't want to wait for moderators to delete posts I reported.
I wouldn't waste time on opinions from people like UnknownO1

Samo stavi i mali disclaimer, npr I am not your financial advisor  

Slažem se s većinom stvari koje si napisao, ali ja se nikad ne bih zajebavao s državnim obveznicama, posebno ne u banana državama.
Najbolje promatrati događaje iz prošlosti i učiti iz toga, čak i ako je to sve modificirano.

Da, i nikada ne zaboravite ovakve stvari...to se može ponoviti za bilo što drugo:

Best choice for you is to stop using so much shitcoins and switch to using mostly Bitcoin.
As a gradual transition you can try using Unstoppable wallet, that works on mobile devices and it is open source, but I am not sure if it support all the coins you mentioned.
Best choice is using open source hardware wallets like Trezor, Bitbox or Keystone because they have good support for coins.
Don't use any closed source or custodial wallets.

BIP39 was created by Trezor developers and it become a standard for most hardware and software wallets.
Electrum wallet later made some improvements and created their own seed phrase system, but they also support importing BIP39 phrase. 
It became popular because it was the first to do something like this, that makes life and backup much easier.

I don't know what you mean.
All wallets are compatible with BIP39, only difference can be with derivation paths that can be different with different wallets.

Mercury wallet is not that famous but I have been following them for some time and I think it deserves a place in bitcoin privacy tools.

I think it was all thanks to SirJohnVonSlotty.
We need more people like him in world we live today, and he clearly proved that he can be trusted with any of his future projects.
I wish him all the best with his new projects and to get married soon, no more time wasting on beach

Only Android base is open source, but rest of this OS is full of junk, bloatware and propriety software code, especially in phones from China, but samsung and other brands are not great also.
Using GrapheneOS is probably one of the bst open source OS you can use for your smartphone devices, it's clean Android OS with big security improvements, but it's far from perfect.
However, I think it's good enough to be used for everything related with Bitcoin apps.

That difference is not big at all in United States, in fact I think more are people in west are using iOS devices.
Percentage would be much different in rest of the world but many people still use cheap Android devices.

This should be true in theory, simply because attack vector for airgapped hardware wallets is usually smaller than for general purpose computers/laptops.
And there is big advantage that hardware wallets can be almost fully open source, that is something very hard to achieve for laptops, but it's not impossible.
I don't see any reason why we can't use both devices and combine them in some good multisig setup.

Not all encryptions are always good, and sometimes they can damage your security.
Telegram claims their are encrypting something, but nobody can verify their claims, and we know many examples of broken encryption in past.
I also remember a case of ''encrypted'' phones used by criminals and create by three letter government agency.

Let's be realistic, nobody stole your money here, you sent it yourself, nobody asked for you to send anything.
Yes I am telling you that you are wasting time doing something that doesn't make any sense, but you can do whatever you want.
If you can't handle simple things than I am not sure you should be using mixers and bitcoin, since you obviously talk a lot with crypto support teams (CM, samourai, sparrow), so this is not your first rodeo.

Again, NOBODY asked him to send private keys to anyone, so he has a habit of doing stuff like this on his own.

They sure look like a scam, but they have totally different design and they are pretending to be centralized exchange, so there is nothing in common with original BestChange website.

If they didn't reply to any of your emails (I don't think this is a good behavior like I said), than I don't see what's the point in sending them your private keys 
I hope you learned an important lesson from your own mistake, and next time be extra careful when you use any mixing service.
There are some grey areas with whirlwind, but most is related with user mistakes that can be intentional sometimes.
And btw most of the neutral people from bitcointalk voted to for WhirlWind not to refund funds in cases like this.

Put yourself in their position, if they start to reply and refund everyone who makes mistakes, they could compromise their security model and potentially get attacked by someone.

This is not exactly the same thing as using a mixer or coinjoin, but it does provide some privacy if you use different address to convert LN coins back to main chain.

There are some wallets (like mercurywallet.com) that work on bitcoin layer-2 with state chains, they are much better for privacy and I think they are working on integrating Lightning Network.
So best combination would be to use Mercury wallet together with Lightning Network if you want to have something very similar with a mixer.

PS
Note that you will have to pay transactions fees each time your are going on-chain and off-chain, and you will have to pay some fees to Mercury wallet.
Doing this for small amount of coins when mempool is full, is not really a good idea.
