Well, there are some people here who had this issue before who are stuck on sending BTC to other wallets or exchanges due to the fee exceeding the total amount of BTC.
What they can only do is wait for the network to become less congested and fees drop suggested by mempool.space there is nothing we can do about this issue.

However, if you still insist on making a transaction while the network is congested you can try to make a transaction with low fees and accelerate it using Viabtc accelerator just make sure that transaction doesn't exceed the 0.5 KB size so that you can submit it to the free accelerator.

I'm a bit confused about what you trying to say but Bitcoin will never become centralized because Satoshi made Bitcoin for decentralization.

If the fees are rising it's just temporary there is something going on that is why you see transaction fees rise just like today because the price touched above $50k that is why people right now panic to move their BTC to the exchange before it drops and make a profit.

What do you mean bull run is close? I think you mean that this is the end of the bull market after the price touched $50k we see a new high price this year but this is not yet the new ATH and it is not the end of the bull market because block halving is not done yet.

You are too excited for bear market be calm this is not the end of bull market we see price jump but that doesn't mean sooner or later bear market comes.

I heard someone that they fixed the issue by downgrading the RaspiOS to version 10.
Others also said they fixed their issue by switching to Debian Bullseye 32bit you can try it and hope it also works for you.

Here's the source where I found it https://forum.blocktrainer.de/t/cgminer-kompilierung-2-fehler/34329/12

Someone is promoting it here just last month https://bitcointalk.org/index.php?topic=5483254.0
You can judge by yourself that there is self-promotion under that thread that makes zyptopay suspicious.  For now, I can't trust them but you can try just make sure to spend only what you can afford to lose.

How about a Visa prepaid card it might be also work on a subscription monthly basis I just found a thread and I think they are still active here on the forum you can check their thread from this link below no KYC required so it should be the right offer you looking for.  The only problem is I  don't know if you can refill the card but try to ask the stealth and maybe they can able to refill the card.

Mycelium should work to send and receive BTC to or from segwit(bech32) BTC address you might be using the old version of Mycelium wallet which is why it wasn't successful when you are trying to send BTC and Mycelium wallet is very problematic it always disconnected from mycelium server or sometimes stuck on syncing so maybe on that time when you are sending BTC from Mycelium wallet the server is offline that is why the transaction fail to broadcast.
I suggest switch to a better wallet like Electrum because Mycelium had this issue since before.

I never heard that there is a Browser Bitcoin wallet if there is one then it is not safe to use and most browser wallet extension that I can find on Google are mostly custodial wallet  like other said "not your keys, not your coins".

And mostly like other said here the browser wallet on brave browser is for web3 usually defi and NFT games that needs to connect to a browser wallets.
Maybe on Metamask wallet you can see wrapped Bitcoin there but that's not a real Bitcoin it is a Ethereum based token supported by metamask wallet.

I did some research and yeah it is a Gaw Miner Fury there is another miner that I found with a similar appearance it is called Zeusminer Blizzard they both use Scrypt algo that can mine Dogecoin and DGB.

It seems this is an old Scrypt miner that only hashing around 1.3mh/s that's not worth running because you can only earn 0.7 dogecoin or around 1dgb a month.
Since the power voltage of this unit is 12v I think running it with solar is the best option power is free and you can mine solo as a lottery for Dogecoin or DGB.

No, it won't compromised it operates the same as other hardware wallets the only use of this is to sign transactions and to power coldcard the seed/private keys are stored in specialized chips it is separate only store secret keys.

If you don't feel safe after you connect it to the laptop there is no problem if you want to rebuild your wallet. You can also disable data connection by going to settings and disable USB data so that the next time you plug it into the laptop it only needs power and no data connection.

Now I see all failed and errors pointed to voltage and yes possible this is a PSU issue.

Is the unit plugged directly into the wall outlet or did you use an extension?
If you are using an extension it might be the cause of your problem because the extension outlet you have can't provide enough power. So try to plug the unit directly into the wall outlet.
Also, check the power cords if it's plugged properly or better replug them, and then test them again.

If not, for a temporary solution would you mind to try if you can run the unit at low power mode you can usually find it under pool configuration. If it works without this voltage error keep running it at LPM but if the issue still persists you don't have other choice but to replace the PSU.

Like others said above you can't spend BTC from your wallet if you are trying to send or receive it to the bech32 address(segwit) with that Armory version it won't work and they already have a newer version that fixes this issue.

The latest version that fixed this issue is Armory 0.96.5 that you can download from the link below

- https://btcarmory.com/0.96.5-release/

You already have some threads about this public key bitcoin generator why did you create multiple threads?
Your concern is already been answered from this thread https://bitcointalk.org/index.php?topic=5484692.0

You just need to make this thing clear because you can generate public key anywhere without the private key offline sample this one below

- https://iancoleman.io/bip39/

download the page and you can run it on an offline device it generates bunch amount of public address if that is what you like.

Now I get it so you are looking for an alternative tool where you can generate a vanity address the old vanitygen only supports legacy addresses but there is another tool that works the same as vanitygen that supports bech32 addresses and can be run with GPUs to speed up the process the tool called VanitySearch check the link below.

You already have a thread here https://bitcointalk.org/index.php?topic=5484547.0 you should check my suggestion first in your thread.

I don't understand what you said above you want to generate a public key from an offline Bitcoin Public Key Generator.
I think you don't exactly understand how BTC address and private key works?

About Electrum what step did you do why it only generate a legacy wallet?
If you are using the latest version of Electrum it should generate a segwit address and then you can later able to export the private key by going to menu> wallet> private keys> export to backup all segwit addresses in csv or json format you can print it if you want just make sure all these processes are offline.

I don't know how this thing works but if you don't want more people to connect to your node then try to play the value of maxconnection I suggest 12 or lower and let's see for the changes on the inbound peers.

Also, play with the maxuploadtarget= according to the link I posted above.

Or try this tool https://jlopp.github.io/bitcoin-core-config-generator/ you can copy their predefined config and paste it into your bitcoin.conf file you can choose between low bandwidth or privacy under a predefined config let see any changes in your inbound and outbound peers.

Why choose? Bitcoin is always there and Valentine's Day is once a year so why would you compare them?

Another thing is even if you are on vacation anywhere you have a phone you can install an exchange app to monitor Bitcoin and take action while you are on vacation.

Wrong section this should be posted on the altcoin mining section.

Anyway, I can't seem to find any custom or modded firmware for this unit Hiveos, brains, vnish and awesomeminer do not support this unit.
If you find firmware from another source online possible it has hidden fees or malware so better stay away from them.

Just adding this you can also edit the bitcoin.conf file or add a bitcoin.conf file into Bitcoin folder if you are using Windows you can usually find it under this directory path below


Edit the bitcoin.conf file and put this inside prune=550 it is MB size you can edit it to higher depending on how much available space is in your HDD/SSD then save restart the bitcoin core and it should sync and download the latest blockchain within this limit.

It should work just fine but don't forget to copy the chainstate folder if you don't want to be stuck in the loading process or else you might end up needing to run Bitcoin Core with -reindex or -reindex-chainstate.
