I have seen such warnings too using my Eset Internet Security. It is just the firewall preventing connection to some of the Electrum nodes that your client tries to connect to and sync. Possibly because those IP addresses are flagged.
Considering that the communication between your client and these servers can not be exploited since the messages and the whole protocol is kept simple, there should not be any risks here.

That's a marketing technique. They do have a github account and there are some unrelated code there and a regular user is not capable of figure out that it is actually closed source so they "trust" the wallet easier. If anyone complains they just give them some nonsense reply about how it is open source (a lie) and how the parts that aren't are because they try to prevent hacking (another lie).

Although the world has been losing faith in US arms ever since they saw how useless they are but I'm still skeptical about this news mainly because South Korea is not an independent country to begin with. It is basically a US colony specially when it comes to military and global presence.

With some small and quick search their military industry doesn't seem independent either. For example the K2 Black Panther tanks that were mentioned in the article is manufactured by Hyundai Rotem which is basically owned by Morgan Stanley which is an American investment company!
Or the FA-50 fighter planes is manufactured by Korea Aerospace Industries with Lockheed Martin (another American "arms dealer")!

I may be wrong but this looks more like an off-shore US military industry selling weapons through a proxy.

I don't know the story here but I wouldn't even begin to consider CZ a "hero" since he is the same person who was offering payment to bitcoin mining pools in order to perform a 51% attack on bitcoin blockchain. All because his shitty platform was hacked and he wanted the money back.

Yeah, I don't get it either. But they entered a lot of other fields too, basically anything they thought was a "hot topic" they created a token for. I saw a bunch in energy field, one was even claiming to "ease" selling oil internationally lol.

Exactly. When we want to introduce an alternative, that should be a better one and have some advantages over the existing system. For example in bitcoin whitepaper these advantages are explained in the first page.
The funny thing is, blockchain is the least efficient form of database so the advantages have to be big enough to justify using it but they don't even exist when they mix it in fields like medicine!

Haha. That's just academia. The students saw a hot topic and thought about taking advantage to start a project, possibly a dissertation and eventually write an article to have that in their résumé. I know because we used to do the same thing although in our field you have to do solid work not some theoretical nonsense without actual work.
For example I spent months working on samples in the lab before I wrote my article on three-dimensional metallography, which was a hot topic those days.

This is one of those "i told you so" moments since we've all been warning about it for years.

The problem is that people can't see the difference between a fake promise and actual peg. What all these tokens do is that they give a fake promise to convert your useless token to bitcoin at a promised rate (eg. 1:1) but they can always break that promise and change the rate to something like 1000:1 if they wanted to and there is nothing the user can do about it!

We have the same problem with stablecoins too since these days many newbies are converting their coins to them. There is no guarantee that  said coins keep their exchange rate. For example 1 USDT could easily be traded for 0.1 USD instead.

This part and your title are wrong/misleading since nobody can "freeze bitcoin" because it is decentralized and transactions don't ask permission from an authority to be included in a block or transferred from one address to another.
The only thing authorities can "freeze" is the centralized accounts that hold IOUs not bitcoins. The IOUs that the centralized platform (eg. the exchange) promises to convert back to bitcoin if you wanted to  withdraw.

In short you should know that this won't happen overnight because bitcoin is not a "get rich quick" scheme!

Considering that you said this is a secondary house that you don't use, it's OK to do this but as long as you understand the risks involved. For example price could continue dropping (meaning you could lose money) for some time or price could stay here but in both cases it could take a very long time for price to go back up for you to start seeing any profit. Can you accept the fact that you may need to wait for a year or two to see profit?

Also you should educate yourself about storing bitcoins correctly in a cold storage so that you don't just lose all that money to a hack or malware or something like that!

You gotta love CZ that uses any opportunity he gets to advertise his own shitty services even though there is no difference between Binance and even their closed source Trust wallet and the FTX schemes.

SECG stands for Standards for Efficient Cryptography Group which is not an encoding algorithm itself but set of standards that define many algorithms one of which is key deployment. It could be a key generated using OpenSSL in which case the file should have a .pem extension and the data should start with 0x30 (sequence tag). But you still have to decode the string.

I suppose they are people like OP who like living in debt up to their necks with an extremely high cost of living that is also rising these days due to high inflation rates thanks to nonstop money printing machines that have produced the highest national debt in the world. That's not even including the high tax rates where the lower class and middle class pay more taxes in one month than the 1% upper class pays their entire lives.

There is human rights issue everywhere. However, it is far less in Iran. I dare say less than anywhere else in the world. Last year alone US police murdered 4900 prisoners, French police is regularly shooting protesters and blinding a lot of them, UK police recently had a clash with idiots protesting against Iranian police and UK police brutally beat all of them and arrested most! in Saudi Arabia they recently hung 81 people for no reason half of them were children from age of 9 to 14.
How many cases you can find from Iran?!

The biggest problem we have in Iran IMO is too much freedom and political representation. Literary anybody is doing whatever the hell they want and say whatever they want. For example over the past couple of weeks a separatist is literary inciting violence in Zahedan (city in Eastern Iran) and advertises separatism. A crime that has up to 8 years prison anywhere else in the world and in Arab countries specifically in Saudi Arabia the punishment is beheading. In Iran on the other hand, due to freedom of speech nobody arrests that asshole.

Except that the negative things you read on social media is produced by US military in their cold war project with Iran. Here is a study by Stanford university: https://stacks.stanford.edu/file/druid:nj914nx9540/unheard-voice-tt.pdf

The reason for being bearish (or pretending to be) on the internet, specially when they are spreading FUD, is that whenever we have a drop like what we had recently a lot of people start shorting bitcoin. Most of them short bitcoin when the drop ended. So in order to make any profit and not lose money they have to see bitcoin price drop more. But as we can see the drop stopped just as fast as it started so now these people are caught with their pants down...

Did you manage to decode the string to its byte array representation to have more information about the actual data?
This project called FinderOuter has a decoder that you could use to quickly check your string with 5 common encoding algorithm used in Bitcoin and see if any of them can decode it and see the decoded data in hex with its length.

I'm not sure how true that is because these LNG supplies are heading for European LNG terminals and the problem there is that the unloading and conversion of LNG is going to take a lot of time which means there is a queue of tankers waiting to be unloaded simply because the terminal is busy!
In fact one of the reasons why gas price dropped was this. They got too desperate to sell their cargo faster that it created a fake "higher supply" slightly decreasing the price.

I'm glad to see others are catching on to this fact. Although it was clear from the day it was created back in 1945. Did you know that we were literary the first country to file the first complaint to UN? It was about the Allies after WWII and it was completely useless

To be honest I had never even heard about him or FTX for that matter before all this drama began. But I agree, all these centralized platforms and centralized shitcoins they keep creating has been harming the whole cryptocurrency world more than it helps it. Binance and their centralized shitcoin called BNB will eventually have the same fate as its predecessors.

The good news is that all these events are making bitcoin battle hardened. A couple of years ago such a scam would have caused at least a 40% dump. Today it only caused about 16% dump and we have been in an accumulation more which many people think is a bear market so the effects should have been a lot bigger.

Total market capitalization is defined based on tens of thousands of shitcoins not based on which exchange get hacked and which one didn't. Their hack also doesn't really have significant effect on the dumping process of those shitcoins.

Are you high?
The scammers and pump and dumpers are not going to give up the shitcion market just because of FTX shenanigans.

This is not specific to altcoin exchanges, but it is happening to all centralized exchanges. Lest we forget that MtGox was a bitcoin exchange that scammed people and caused a crash in 2013.

I agree with your general tone about bitcoin being the only viable option and altcoins being useless, but I'm not sure what you are suggesting here is true about bitcoin being able to fix the issue with centralized exchanges and the risks involved when using them. The only viable solution to the CEX mess is to start using DEX.

Technically speaking a peer to peer network is a network without a need for "central coordination by servers or stable hosts", in simple terms there is no server/website that peer to connect to. They directly connect to each other. So a centralized P2P can not even exist.

Take a look at this topic that lists different encodings https://bitcointalk.org/index.php?topic=4959742.0.

But the problem here is that your string is using a nonstandard uncommon encoding and data structure, it is extremely difficult for us to "guess" what it is! It could be literary anything from arbitrary data that has nothing to do with bitcoin private key to encrypted key including the IV and extra information which again requires knowing the algorithm used to be able to decode and decrypt it.

You should start by first figuring out the encoding that was used to encode the data here (eg. base64).
Then decode the string to get the raw bytes out to know the size (eg. 68 bytes).
Then you have to figure out what part of it is the key which is 32 bytes (eg. first 32 bytes is the key, the second is the IV and the last 4 bytes are salt; or maybe first is salt, second key and finally IV).
Then you have to figure out the encryption method used (eg. AES256 ECB or CBC or ...) and where the salt (assuming it exists) were used (eg. in scrypt or PBKDF2 and with what settings).

So as you can see it is better if you tell us how you came across this string and why do you even think it is a bitcoin key?
