I do not think that this virus was so sophisticated, but it was changing all the things you copied and similar to the Bitcoin address to another address or the address of the hacker while hiding all the methods of scanning the QR so that it was difficult for you to detect scam.
suck hacks are for newbie or who makes fast exchange and doesnot check address.
In general, such viruses need access to the permissions of the core, which means that you have installed programs from an unknown source or an update from an unknown source.

Next time avoid download any unknown app/service.

Most exchanges haven't updated their code in a long time so unless there is a good motive forcing them to use lightning I don't think they will and I can cite several reasons why they don't:

 - Withdrawal of altcoins: One of the reasons for withdrawing altcoins is because of the cheap withdrawal fees or transaction fees. If the Lightning Network is implemented, most of the altcoins will be inside the platform and will not be withdrawn.
 - Channel Closing Fees: The Lightning Network is good for those who want to make small and frequent payments other than what happens on the platforms (large and rarely daily payments)
 - More effort, less return.

What drives the market is supply and demand, which can be influenced and use the news to make a small event seem big and vice versa.
The news channels are also trying to find a logical justification for increasing or decreasing the price, although that justification may not be true, but everyone believes it.
Suppose, for example, that the price of Bitcoin rose 10% (a natural thing) and at the same time something happened, such as a player in the English Premier League watching a Bitcoin movie, you will find some news channels linking the two events, which is exactly what happens with Elon Musk’s tweets.

I hope you get your money back, but the nature of the case here will be determined by the Japanese judiciary, which I do not think is different from the American judiciary.
Generally, the money is supposed to be refunded in bitcoin because it is an asset, but due to the nature of it has not been officially recognized, the ruling will often be to convert that money to the national currency and recover that money for all people who lost their money with the possibility of recovering the recovered currencies and return them to them as bitcoin.

so your chance for getting your BTC is less than 15% but will will get part of it.

I found this quote for how  Samourai Wallet Ricochet transactions work. Overall, it is unfortunate to see that few people focus on privacy and try to make Bitcoin harder to track.
There are already many mixing services, but the reason you are mixing determines which one is suitable.
They all try to break the link between the sender and the receiver, and unfortunately, they all fail if they are analyzed well.
The only way is to change the owner of the private key, but I can't find any site that offers this service in a decentralized way.

Bitcoin is always present in the blockchain or stored in it and you keep the key that enables you to access those currencies.
The method of accessing these currencies determines whether you trust third parties to manage these keys (exchange platforms, governments, banks, etc.) or use a program to manage and generate these currencies (a wallet, whether it is open source or closed source)

From here you can ask your questions about how to protect and secure those keys that enable you to send bitcoins.

We can't judge it's over, but it's not as popular and insane as it was a few weeks ago.
The market needed a correction period, so it is not unlikely that we will return to the previous levels and break them, but not all currencies will succeed in breaking those peaks.

Even ICO/IEO/HardFork has a little noisy, but it's getting cold.

I don't know what I understood well, but the model for the two cryptocurrencies you are talking about is different and there is nothing that brings them together. Also, there is nothing special in doge's coin except for the intense promotion that happened to it on the Internet.
In other words, the benefit of WBTC was that they could be traded as tokens and used in decentralized platforms not like WDOG

The price did not achieve noticeable rises, but like the rest of the cryptocurrency market, it rose because we are in a price bubble until we did not break the previous peaks.
The reason for the recent rise was the network's lack of images or non-fungible icons, however over time there was no change in the price.
I don't see any future reason to keep this currency. The cheap fees that the network promises are limited and you can get better ones in other networks.

BCH after some years = 0

I saw many newbies using that wallet. Therefore, it is easy to scam them and convince them that this wallet is real, especially the one that carries the .uk site.

I don't think Google will be serious about fighting this type of fraud unless there is legislation from the United States or many people who have lost their money sue Google or stop using the search engine.
It is unfortunate that Google supports this type of fraud, but things will change in the future as the number of users increases.

I don't think the idea of getting email notifications is an idea that people, or at least people in this forum, are looking for.
Why not try to add other ways to get news like creating an account, Telegram bot, and others?
This site offers a good service in tracking news ----.> https://coindar.org/. If you can add more filters and improve their quality in predicting prices then you will get more attention.

I've read some of the comments above and some of the issues described above still exist.
The site is running slow, there is no focus on the interface, the response is late and many charts are not working.
Also, the essence of the idea is that it is not unique as there is nothing innovative that the site has provided.

In general, a domain name is easy and with some effort we might get something good.

What do you mean by the word "we" that kept repeating? It is strange to present yourself as a legal mediator and you are not providing any information about yourself.
What are the previous experiences? Which country is your jurisdiction, and some of the services you provide require that your team have some technical information and technical expertise.
Overall, if you can prove the experience and the right team, I think it's an excellent service.

The difference here is in your need for money and the reason that prompted you to buy Bitcoin, some people like speculation and others are long-term investors.
In many cases, doing nothing is an ideal investment instead of following and analyzing the market to determine entry and exit points, and in the end, you lose all your money due to a wrong movement in the price estimation, after which the price rose 100% and did not return to decline.
Just like they did when bitcoin rose from 8k to 11 at the end of last year. it was a good earning but holding will give you 65k or 35k at current prices.

I don't think Cardano has smart contracts or they haven't been activated it yet,
Most of the so-called smart contracts are represented in the ability to create tokens and make exchanges, so we only need two or three main blockchain and the rest will be a repetition of previous ideas.
I also think that if we were able to create parallel contracts and the ability to make cryptocurrencies talk to each other and carry out transfers, the need for many tokens would end.

Regulation will end the speculation and therefore there will be no use for these tokens

I don't know, but I think that most people who bought bitcoin this year believe that Elon Musk is the CEO of bitcoin and therefore his tweets will contribute to the price?
Elon Musk’s tweet has nothing to do with what happened today and a 10% volatility is normal in Bitcoin and may happen without there being any news or a real reason for such volatility.

In general, stay away from following the Elon Mask tweets and base your investment decisions on something more accurate.

It is best to hide your friend's withdrawal address for privacy and security reasons.
Accounts are usually suspended/hold for either sudden activity in the account or a request for further identity verification.
If your friend is ready to verify the identity and has proof that he is the person who purchased these coins, you will be able to withdraw them after communicating with the support team and sending the required data.

In general, you will need to verify identity.

I'm not a fan of Gamers challenges but I think most of them make money by doing live broadcasts during the game. If this is the case, then privacy is not a priority for them, so it makes no difference whether identity verification is mandatory or not.
In general, we are finding use of Bitcoin instead of speculation and quick profit, but I do not see the actual value of Bitcoin in this case. Any token can be used in this case or the possibility of withdrawing (with cryptocurrencies instead of cash) if you do not want to verify the identity.

The age of the industry does not exceed a decade, so there are no university degrees specialized in it, and the demand for it is increasing every day, which means that your experience in this field will guarantee you a job opportunity faster than the rest of those seeking employment. Therefore, studying and learning blockchain technologies will have a quick and rewarding return.

Also, do not forget that there is another opportunity, such as being paid in cryptocurrencies.
anyway don't trust any thing from blockchain.com.

User-targeted attacks are rarely so sophisticated, many people are fools to be deceived in simple ways, so following some simple steps will make it difficult to get hacked.
Ensuring a padlock will not make you 100% safe. Encryption means it is hard for the third part to read any your password but the site can read it and hacker may read it if your OS have some backdoors.
