Stablecoins have huge business potential. 🌋
They bring some of the advantages of bitcoin and request smaller leap for people. People think in the same currency and receive more options.
Still, I can’t shake a certain bad aftertaste. 🤢
Bitcoin doesn’t appeal to me because we want to improve fiat. I consider fiat a criminal tool for robbing the uninformed — people who naively save in it their whole lives and never actually accumulate anything. An asset the state can block, devalue, or outright steal at any time.
If a stablecoin ecosystem is successfully built, I believe it will be even harder for people to leave the polished cage.
There is only one Bitcoin. Stablecoins are a polished fiat (scam).

Nostr jako sociální síť u nás nikdo moc nepoužívá. Nicméně je dobrá šance, že ho využijeme jiným způsobem. Například při komunikaci více Suit mezi sebou. Konkrétně třeba bezpečná výměna adres bez nutnosti interakce uživatelů.

My friend recommended me to round up to hundreds of sats when paying in bitcoin. I may pay few peanuts extra that way, but I like the effect of it suddenly not being a random string, but a much more understandable number. When paying repeatedly (ie for lunch), you can see how both parties perceive the sats amounts right away after a few repetitions.
I remember cheap lunches at 16,000 sat, today even 8,000 sat for lunch seems too much.

Trezor Suite 25.5.1. has increased fee rate granularity. It’s better adapted to current low fee environment, but works even in other scenarios.
You can set your desired explorer to for example @npub18d4…6lt3.
We have renamed `bump fee` to `speed up`. Following industry pattern just like for example @npub1jw7…35fg does.
The Suite now closes instantly, which also makes it easier to quickly hide it in shared or public spaces. There are many other improvements - maily small UX fixes.
You can demand the update in settings.
Join early access program if you don’t want to wait till next week with the release.

You lock your bitcoin. Based on that receive the fiat. Once you pay back your bitcoin will be unlocked. If you don’t pay back you can lost your locked bitcoin. It’s 2/3 multisig between you, counterparty and firefish (mediator).
If the price of bitcoin dumps you are prompted to increase collateral. In the worst case you will keep your fiat and counterparty gets your bitcoin with nice exchange rate 🥲

2025-02-24 05:32:50

I see verified contacts as the most important feature to develop right now. It may not seem revolutionary on its own, but I believe it is a fundamental building block for a resilient P2P network.
- You verify your contact’s identity (npub) in your hardware wallet.
— This is best done offline. You don’t need many contacts, just ones you fully trust.
- When sending an on-chain transaction, you use an address signed by that contact.
— This means you don’t need to check the address on your HWW, just the human-readable name tag.
- The verified contact’s address can be automatically retrieved in the background.
— We tested this using Nostr in our prototype, and it worked well.
- The same approach can be used to verify anything else.
— For example, LN invoices or Ark addresses.
- This could also enable:
— P2P marketplaces
— Social backup
— Trust-based scaling #note174q…d5y4
Ideally, a high-quality standard would emerge that various HWWs could adopt. This would allow deriving backups for any hot wallets, and verified contacts could be used consistently across all applications.

2025-02-23 19:58:04

- reply

I have an idea, but not working specifically on this part of it right now.
1: Derive contacts (npub/npriv) from seed (ready in Trezor)
2. Verify offline your trusted contacts (TBD)
3. Derive shamir that leads to the same result as initial seed (already working in Trezor)
4. Encrypt these shares with previously verified contacts
5. Store it securely - there are more options with various trade-offs- it could be shared directly with your verified contacts, it could be recorded on blockchain (that enables automated health-check, but you can’t remove the trusted contact later on), or you can store it on your(or trusted) node/server → that enables later changes and health check - server can’t misuse these data since they are encrypted.

Good point

2025-02-23 08:20:49

I’ve seen estimates suggesting that around 200 million people own some bitcoin, but only about 10% of them hold it in self-custody.
If roughly 2.5% of the world’s population has some bitcoin, I assume they, on average, hold only a small portion of their cash in it.
So, I agree—the potential is huge, and bitcoin is accessible to anyone. 🤯
However, even if your savings increase tenfold, there are more efficient ways to build wealth.
My main point is you shouldn’t kidnap bitcoiners—there are wealthier targets out there. 🫥

2025-02-23 07:59:23

Basically anything you save from month to month can be stored in bitcoin

2025-02-23 06:55:45

People often think that if you have bitcoin, you must be rich.🤑
But just saving a bit of what you don’t consume doesn’t mean you’ll be wealthy. A moderately successful entrepreneur who has never even touched bitcoin will likely be better off than an average bitcoiner.
Bitcoin brings freedom and protection against poverty, but the days when it made people wealthy are long gone.

2025-02-23 06:45:56

Speculating on the price of bitcoin is a distraction. If you're not willing to go all in, it's hardly worth it. The most common advice is #DCA, but I recommend going all-in with #GetOnZero.
If you have an income that covers your needs and you believe bitcoin is better than fiat, then keep everything in bitcoin and stop worrying about nonsense.
I've been doing this for several years, and it's incredibly liberating. It also comes with many other benefits, such as:
- You’ll learn to use bitcoin more effectively
- You’ll always prefer paying with it
- You'll start building a network of bitcoiners around you - especially within your family.
- You'll be able to help people because, with your established network, you can - for example, send something to your mom, knowing you have several other people to replenish your bitcoin supply.

It feels like every application is addictive in its own way.
I can sense how, with almost every use of a custodial wallet, my vigilance decreases, and I become more comfortable keeping larger amounts there. Switching away from it gets increasingly difficult.
Cashu wallets offer an easier transition between banks… but I still miss a smooth path to self-custody. It almost seems like if you don’t start with self-custody from the beginning, it becomes more distant rather than closer over time.
