To "crack" a Bitcoin private key, in the sense of finding the private key from a given public key, is a problem that falls under the general class of quantum computing attacks called Shor's algorithm, which could factor integers and compute discrete logarithms much more efficiently than any known classical algorithm.
The Bitcoin address corresponds to the hash of a public key, derived from a 256-bit private key through the elliptic curve digital signature algorithm (ECDSA). This 256-bit key would require a quantum computer with around 3072 qubits in order to break it using Shor's algorithm, due to requirements of qubits for error correction and for storing intermediate results.
However, as of my knowledge cutoff in September 2021, we don't yet have quantum computers capable of executing Shor's algorithm on numbers anywhere near this large. The largest number factored by a quantum computer using Shor's algorithm as of 2021 was only 21, which was accomplished using just 8 qubits. In fact, there is much skepticism in the scientific community about whether it's feasible to build quantum computers of the size required to break ECDSA 256-bit keys in the near future, due to issues with error correction, qubit stability, and other technological challenges.
Moreover, even if a sufficiently powerful quantum computer was developed, the Bitcoin protocol could be updated to use post-quantum cryptographic algorithms, which are believed to be resistant to quantum computing attacks. Many cryptocurrencies are already working on post-quantum cryptographic solutions.
Luckely for me the coffeeshop is around the corner
Unfortunately that is not true.
If it was true there was no post quantum standarization needed

Hope it is a hoax because #bitcoin is not post quantum ready
Iris now supports secret chats that don't leak metadata, implementing the https://hrfbounties.org/ bounty #3. It works also for group messaging.
It's a quick & dirty solution, but works. A shared nostr account is created for the secret chat / group. Its nsec can be shared via link, qr code or invite message from a single-use anonymous account.
Users can then communicate using the shared account's messages-to-self. Iris signs the inner messages with your own key, but the arrangement could be used for anonymous group messaging as well.
I'll also add inner message encryption at some point, so you can ensure that only certain group participants can read the message.
This arrangement doesn't introduce any new event kinds and works also in clients that haven't implemented a special UX for it. You can just log in with the nsec and message yourself.
I had to disable the Iris social graph filter to let invites through, so now Iris DMs are open to spam again, but I'll try to figure out a better solution.
As always, the UX needs a lot of attention, but I believe here's an MVP.
Screenshots:
Alice wants to message Bob:

Alice sends a secret chat invite to Bob:

Bob automatically follows the invite from Alice. They can now message each other in the secret chat:

Here's how the invite looks in another client. I will add an "nostr:ninvite" URI in addition to the nsec.

Looks like this:

After that: eyeball torture.
Will he still refuse to give his keys...?
The ones I have spoke do know the system is broken. But they simply do not care. I tried in 2010 to convince many of my friends without succes. They see now they are wrong, I did quit my job in 2017. Even gave in the period 2010 many coins as a presence, which they immediate spend and did not have any believe in it. Again my experience. But it is now centainly not to late, but they simply don't care enough. That is my experience.
Dunno hope i'm wrong. Majory in this world keeps poor. Always have been.
They have to find out the hard way. But then it's to late for them.
nostr:npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m, please help SimpleX to create a web client. After that, I can integrate it on NostrNet.work, allowing users to seamlessly use it instead of Nostr DM.
You can both also create a new keypair (only known to you and other party) and then DM with each other. Problem solved
Me too. It's called life.
If old habits can be changed bitcoin is also not safe anymore for a replacement. For that reason alone let's hope Xitter stays the no 1.
ChatGPT4 Makes this about your message:
The phrase you've shared contains a lot of Australian slang. Here's a translation:
"G’day!" - This is a common Australian greeting, similar to "Hello" or "Good day."
"How’s it going?" - This is asking how the person is or how things are going for them. It's similar to "How are you?"
"My ankle biter killed me yesterday." - "Ankle biter" is an informal term for a small child, likely referring to the speaker's own child. "Killed me" probably means that the child exhausted or overwhelmed the speaker with their energy or needs.
"I’m knackered." - This means the speaker is extremely tired.
"Might have to bail on the barbie." - The speaker is considering cancelling or not showing up to the "barbie," which is short for barbecue, a common type of social gathering in Australia.
"My mate lives out whoop whoop." - "Mate" is a friend, and "whoop whoop" is a colloquial term for a place that is considered remote or far away.
"Too far, can’t be fucked." - This means the speaker is saying the distance is too great and they can't be bothered or don't want to make the effort to travel it.
"I’m cactus." - This is an Australian phrase meaning they're done in, exhausted or at the end of their tether.
So a paraphrase of the whole phrase could be, "Hello, how are you? My young child really wore me out yesterday. I'm extremely tired. I might have to cancel on the barbecue because my friend lives in a remote place. It's too far away, I don't have the energy or motivation to go there. I'm completely exhausted."

After a while Amethyst crashes probably due to many badges.
I use nostdress for this.
Probably already known by many
