I'm a bit confused about what you're trying to say here. Just in case you misunderstood me, I'm not using a Hackintosh but a Macbook Air M1 with a dock (from a third party, did not buy it from Apple), which is why sometimes I have issues with my connection. That's why I ask you whether you have the same setup as me or not because if that is the case, the culprit is probably your dock or your Mac version, not Electrum itself.

At the end of the day, since you solve the connectivity issue by updating, it's clear that Electrum is not the problem.

I don't look at the rest that much but this case seems like a classic victim of phishing. Whether he uses Exodus or not doesn't really matter if he inputs his seed (or passkey, as he mentioned it) to some random website, after some random guy that said he is an Exodus employee told him to do so. That being said, I do agree that it is better to use other apps if there are too many cases where users' funds are stolen without any clear reason why. CMIIW.

Anyway, has your issue been resolved OP?

Most of the popular ones mentioned above support USDT, or other stablecoins if you're interested. Just check their about page if you're unsure, or use a search on Google with simple keywords like "Coinpayments accept USDT" to see if they accept them or not. Self-hosted BTC payment gateway usually only supports BTC though, CMIIW.

As for detailed fee comparison, I think you'll have to compare it yourself if you want some in-depth analysis. I found some simple comparisons online but the information is usually outdated, and most users here would probably use BTCPayserver anyway. You can probably find this thread useful too[1]. Some posts on that thread have good suggestions if you want to look further, but keep in mind that most of these are BTC payment processors, so you have to check manually check them to see if other cryptos are available or not.

Unless I'm mistaken, OP friend uses Bitcoin Knots, which is a fork of Bitcoin Core. It is a decentralized wallet where you manage your own coins, I doubt any support will be able to help them recover his password other than suggesting some methods that have been mentioned above.

As far as I understand it, BTCrecover supports variations of Core like Bitcoin Unlimited, XT, etc, so I think you can give it a shot even if Bitcoin Knots is not explicitly mentioned. CMIIW.

Yes, that's what I understand too. However, I believe other explorers also have a similar function. I can see the appeal for an all-in-one revoke tool for different chains though, but if I don't use that many chains maybe I'll stick with an explorer instead. But, I might be interested if the tool is open source and can be verified by others, regardless if I use multiple chains or not.

I see. Do you plan to publish it on your GitHub then? If that's the case, I'll probably wait until the code is available to use the platform if I feel the need to revoke some contracts. I believe some people don't feel safe using a closed-source platform even if it's so convenient unless we use a throwaway wallet to test the tool.

What's the difference between your tool and using another tool like Etherscan built-in revoked, or Revoke.cash other than the support for multiple networks? Also, is there no plan to publish the source code so others can verify it? Some of your competitors have a Github page/open source code, if it were me I'd be more interested in using them regardless of whether I can verify it or not. Especially after the recent fall of some exchanges, so many scams using smart contracts, etc.

They have a huge market share and some buyers don't really care about the ripoff I guess. But they definitely took it a bit too far this time because almost all reviewers and your average joe refuse to recommend their GPU due to the insane pricing. Hopefully, AMD can be better next time, even though I feel like it might take a few years or that's too much copium too.

I might be wrong but I recall seeing some posts/news about some stores refusing to accept returns/refund for GPUs. Can't find it anymore though. It is not really impossible if a store implements them though, especially if the buyer is suspicious.

If I understood it correctly, the point is not about KYC but what currency they use. I mean, you can't really say a platform is a crypto platform if they don't use crypto at all, but you can still call a marketplace a crypto marketplace if they accept crypto regardless if they need KYC or not. I do agree that KYC is really a pain in the ass, and considering how many companies leak data recently, I'd stay away from any centralized platform for now.

As long as there is no recent thread that asks the same question, I also believe that creating a topic to discuss some questions is okay. Obviously, the "recent" part is debatable but as long as it is not within days/weeks and the discussion is not yet dead, I think it is fine to create a new topic to discuss the question.

I think you can refer to this[1] faq if I understood it correctly. While it does not explicitly confirm that winning is calculated on fiat or crypto, it at least confirms that crypto is the preferred way to show your balance, hence the fiat values will fluctuate.

Most exchanges will require some sort of KYC registration if you're dealing with fiat, so if you plan to use another exchange make sure you check out the verification first before you transfer any money. I see your posts and it looks like you did transfer money first before you found out that you need KYC (regardless of what is your purpose of depositing and withdrawing quickly), I hope you can stop doing that since you'll likely end up losing a lot of money if your KYC fails. If you don't want any of that I suggest checking Bisq if you just want to buy BTC.

No one can help except the support itself. Try to pm or send an e-mail again to the profile linked by omega above. Try to contact their support again when you can, wait for a few hours or try at another time. If that doesn't help maybe make some noise on their social media.

Give it a few more days maybe. Some representative stays offline for some time from time to time but if they are online most of them will respond to your thread afaik.

I'm a bit confused by your "only know 1 character" statement. How did you know it consists of 30+ characters if you can only remember 1 of them? Are you sure you don't keep any backup of it anywhere? Did you use a password manager to fill in the password in the past?

If your wallet doesn't contain that much money, maybe you can let it go since brute-forcing the rest of your password will take a very long time as others have mentioned, at which point you probably made more money by doing something else for the next few years. Try to keep a backup of your password next time maybe, use a password manager like KeePass so you just need to remember one strong password and let KeePass handle the rest. CMIIW.

Thanks for all the replies and suggestions. Fortunately, most of my passwords are good enough at least by today's standards. Unfortunately, some services that I use still put such weird limitations on password characters that weaken the security.

True. I wonder why they do that, I don't think it takes many server resources if I can use a 100 characters password or something similar. Fortunately, most crypto apps don't follow the same thing.

Thanks for the info. I already know this but I just want to try to test the security with another reliable tool, if there is any. That being said, I probably should avoid websites like that unless it's absolutely necessary to use them.

You need to report the apps if you want them to check whether it is a scams or not. Google seems to use a bot with a preset that allows malwares to get listed as long as it passes some surface-level check. That being said, I'd also be cautious even if you use another app store like FDroid as long as the developer does not provide a way to check whether the apk is legit or not.

It is not that difficult as far as I'm aware. Sometimes a developer provides an MD5/or other forms of a hash of the apk so you can verify it. Other times they provide the code so you can build it yourself. Just in case everyone is not yet aware, don't get fooled by SSL certificates. Some fake websites can use free SSL encryption to trick users. Make sure to double-check the address regardless if it uses SSL or not just in case you get phished. CMIIW.

It's definitely not a loss, as long as the cost is justified. Some businesses probably only have one or two countries as their customer base, so it is also understandable if they don't think an app is necessary when the website is good enough.

Sounds like it affects many different kinds of mouses. On that thread, both wireless and wired mouse are mentioned (I assume it's from a different brand too). If this is true maybe the issue lies in the Trezor suite itself. I never see any complaints about it on my local board, so it is news for me too.

My PC also has this kind of weirdness. Sometimes it won't boot up if I plug in a USB device on one of its USB slots, but after it boots up I can plug and play on that particular slot just fine. On rare occasions, it just decided to stop booting up unless disconnect my power first. Tried to see if anyone has the same issue on that motherboard but it seems that it only affects a minority of us. Hard to figure out what the issue is if it's hard to control the test environment, especially when it is never consistent. My gut feeling tells me that your mouse is probably fine, it's your laptop that is unique. CMIIW.

Can you clarify which second connectivity issue are you referring to? In my case, I do have some occasional network issues with my Mac if I connect it to a dock, but this applies to the device itself and is not exclusive to Electrum. I find that with 12.2.1 my network is quite stable, so in my case, it is probably a dock incompatibility issue with the latest mac.

From the way you post it, it sounds like this stablecoin project will be a major one, and they will use it for any transaction that happens in their country. Using a public blockchain, run by who knows who across the world, has no guarantee that they monitor it for malicious purposes or not, that probably has some bugs like the latest address poisoning attack, is very risky IMO. Unless they don't plan on having any control over the node/network, which I highly doubt is the case here. CMIIW.

There are also Harmony, and others altcoin project who promises high TPS but sacrifice some security. OP's friend can probably fork and modify it. Just make sure that some of these projects are also a fork of another (mainly ETH), and it might share some bugs because of that. Btw, since CBDC[1] is a trend now, maybe you can suggest your government ask for some feedback on how others do it, whether they want a shared blockchain or not, etc.

Does this mean you did a face verification before, but this shows up again when you tried to withdraw your DOGE? That's really bad. I wouldn't be surprised if one of the programmers messed up and make the trigger for extra verification become stricter or something similar and then was too ashamed to admit it.

Be careful if you're looking for another CEX. So many of them require personal data and keep requesting you resubmit every few months or so. Some even ask you to submit a passport and claim your national ID is expired even if the government stated it is valid forever. I believe collecting user data is probably necessary for them so they can 'share' it and earn extra income. It's unfortunate that there is still no great platform for altcoin trading that doesn't rely on a centralized party (by great, I mean with great liquidity, fast order, etc).

Other than the cheap electricity mentioned above, you can also wait until the difficulty becomes much lower if you really want to mine and make a profit out of it. The bad news is, nobody knows just how much lower it will go, or if it will ever be at all. I've seen some news talking about miners selling all of their BTC just to keep mining, but it's hard to know how much is the truth on that report since we don't see any change in difficulty yet.

There are many tools that you can use to check them out. I suggest visiting the altcoin board for more details. For example, whattomine is a website that you can use to see which coin is mineable and how much profit you can earn daily if you use GPU A or B. While the cost is arguably lower, if you want to make a profit quickly, maybe you should look for other alternatives. CMIIW.

I can find this sign/verify page on BSCscan, are you referring to this[1]? It supports MetaMask and WalletConnect. According to this page, SafePal does support WalletConnect, so it's not impossible for you to create a message and sign it[2]. I never tried it myself though, since BTC-signed message is more common here. CMIIW.

The address book/contact feature is really helpful. Sadly not every wallet has it, and not everyone uses it either. I don't know why but I found some users still copy-paste addresses from their transaction history or blockchain explorer. I don't think it's convenient at all unless their wallet is really terrible and has no built-in feature for copying addresses. CMIIW.

Does that mean they don't plan on solving the 'bug' that allows address poisoning to happen in the first place? Improving blockchain explorer sounds good but I would rather stop using a network that allows a bug like this to exist in the first place.

Is there any reliable tool to test whether a password is weak or not? I'm aware of some online websites that test your password entropy but I don't feel safe using an online website for it. While I can download the page, the question of reliability comes up. I've been using KeePass to generate at least 100 bits of password for every account that I use, but some websites or app, unfortunately, doesn't allow creating passwords with more than 8 characters.

Fortunately, most wallets don't have such limitations. CMIIW.
