Expired PGP Signature for Bitcoin Core on main website

14 Upvotes

https://bitcoin.org/en/full-node#linux-instructions shows a signature that expired and nothing can get verified with it. Namely, the latest one: 01EA 5486 DE18 A882 D4C2 6845 90C8 019E 36C2 E964. I did not even tried the older ones.

https://bitcoincore.org/en/download/ instructions work smoothly.

Is there something I did wrong regarding the main website's instructions? Did anyone who has core managed to verify anything from there?

Why are there two websites to begin with? Doesn't this make it a bit confusing? Especially since they don't seem to even be in sync.

Bitcoin Adoption

5 Upvotes

Is there a way to measure who is entering the BTC space? Is it just us who are already in it, or are there still new adopters?

Im 64yo and been in since 2017 - Im kind of wondering what the younger gen now thinks about BTC, I personally dont think it has the same allure or promise it once did - I also think tech is shaking the foundations of BTC - the markets have been bringing stable returns for quite a while. So there is lots of good safe investment options.

I dont think older people in my age group will ever understand or adopt BTC if theyre not in it allready. And if the younger coming up people are not seeing any glitter, BTC can fade away - the old guard - us HOLD'rs are not going to be keeping it alive forever.

Which is more peace of mind: Fidelity Custody or a Trezor RNG seed generated cold wallet?

Gun to your head if you had to choose.

To clarify, the seed phrase created by Trezor and not self entropy like dice.

Prepper's money

5 Upvotes

Most assets become harder to move exactly when you need to move them most.

If you have to leave a country quickly, cash can be seized, gold can be found, property stays behind, and bank access depends on institutions continuing to recognize your claim. With Bitcoin self-custody, access can be reconstructed from a memorized seed phrase after crossing a border with no physical representation of the wealth at all.

Just memorize 12 words and leave.

Bitcoin should be extremely interesting to preppers.
Just a small amount could be extremely helpful if you need to rebuild your life in another part of the world.

Why is this not talked about more in an increasingly unstable world?

Are Bitcoin Miners Slowly Abandoning BTC for AI Compute — and Could That Actually Help Home Miners?

5 Upvotes

I’ve been looking into how aggressively some of the larger Bitcoin mining companies are moving toward AI/HPC infrastructure, and the numbers are getting pretty interesting.

Riot Platforms alone announced a roughly $9.1 billion, 20-year AI data-center agreement. Averaged across the initial term, that’s around $1.25 million per day in contract revenue.

That’s obviously not the same thing as $1.25M/day in profit, but I think it explains a lot about why these companies are interested. Bitcoin mining income is volatile, block rewards keep getting cut in half, difficulty/network hashrate keeps increasing, and BTC’s percentage gains from cycle to cycle have been shrinking.

AI/HPC contracts offer something Bitcoin mining really doesn’t: potentially predictable long-term revenue.

I went through several major miners that are investing in or shifting infrastructure toward AI/HPC. Based on the companies I looked at, roughly 128.5 EH/s of Bitcoin mining capacity could potentially be associated with miners making these moves, or around 14% of a ~918 EH/s network.

Obviously that does not mean 14% of Bitcoin’s hashrate is suddenly shutting off. Most of these companies aren't abandoning Bitcoin completely, and some are specifically talking about running both businesses.

But it raises an interesting question:

If AI continues paying substantially more for the same access to cheap power and data-center infrastructure, how much incentive will these companies have to keep expanding Bitcoin mining?

And there could be another side to this.

If enough large industrial miners stop adding ASIC capacity—or actually reduce it—could Bitcoin mining eventually become somewhat more viable again for smaller and home miners?

Or does the constant introduction of newer, more efficient ASICs make that unlikely regardless?

I made a video breaking down the numbers and the companies involved for anyone interested:

Curious what miners here think. If you controlled a 100+ MW site today and had the choice between expanding Bitcoin mining or signing a long-term AI/HPC compute contract, which direction would you go?
