BTC's Luke Dashjr: '24 Bitcoin Core Update Will Disrupt Ordinals, BRC-20
get some theory of mind. you are a person who is willing to pay onchain fees to use your trezor or open a channel. there are people in the world who are not willing to pay these fees and they probably outnumber you. and the plan has been spelled out in plain english a million times. the fees are supposed to go up by design. this means that most people will not self-custody, whether it is legal or not, and even if they would like to.

Meaning of display numbers.
I’m not an expert so someone smarter than me can clarify, but the high/priority rate is the going rate (estimate) to get confirmed on the next block. Medium is the average rate for those transactions to be confirmed next. You can see current and historical rates at mempool.space.

BTC transaction fees, WTF?
Check mempool.space for a better idea of how big a fee you need to offer to get into the next block.

My First Bitcoin!!!
The mempool is a bit crowed now. A few weeks ago it was only around 5 - 10 cents, and now it is between 3 and 13 dollars. (yesterday even 25 dollar) If you have a lot of UTXO's it can be very expensive to consolidate them all. In that case I would wait till the mempool is less crowed for lower transaction fees. it is important to understand that whirlpool or wasabi wallet will take many UTXO's (transaction fees) to mix your coins and maybe in the future exchanges don't want to touch your mixed coins. I mixed all my KYC coins as I'm not planning to exchange my bitcoin for fiat via a exchange in the future.
- If the answer to high onchain fees is using layer 2, how do you get your layer 1 btc on layer 2 without encountering the same high fees?

Coldcard post anti-forensics for paranoid people
As you can see, the default firmware of Coldcard is hardcoded with values d13e and cc10. We are going to change it to make it look like a benign USB device, more on it later. First, clone the original firmware from Github: https://github.com/Coldcard/firmware We now need to edit the file called ./stm32/COLDCARD/shared/usb.py: COINKITE_VID = 0xd13e CKCC_PID = 0xcc10

Hardware/Software wallets and backdoors implemented by different nations?
Software altered? You were supposed to download from source and flash it yourself. So why did you alter it? No one other than you could have altered it! https://github.com/Coldcard/firmware

Is it safe to buy bitcoin on a fidelity account?
Coldcard has many other security features as well. You can find more about them online. Probably the safest hard & cold wallet on the market right now. But most people don't buy it because of their $400 price tag. But definitely worth it for anyone holding more than a pretty penny.
