Ein wichtiges Thema für den Bitcoin-Standort Deutschland.
Die steuerliche Behandlung von Bitcoin betrifft längst nicht nur Anleger, sondern auch Unternehmen, Payments, Lightning und neue Geschäftsmodelle.
Deshalb halte ich dieses Positionspapier des Bitcoin Bundesverbandes für besonders wichtig.
Positionspapier des Bitcoin Bundesverbandes zur steuerlichen Behandlung von Bitcoin in Deutschland.
Wir fordern: Haltefrist erhalten, klare Regeln für Bitcoin-Zahlungen, Lightning und Self-Custody schaffen – und den Standort Deutschland nicht durch unnötige steuerliche Hürden schwächen.
Besonders bei Micropayments, Machine Payments und AI Payments braucht es einen Rahmen, der Innovation ermöglicht.

69 blocks left until mandatory BIP-11O signaling.
Have my fork.observer connected to a mix of 50+ nodes: Bitcoin Core, Knots, BIP-11O, btcd, floresta, electrum, and mempool-space. Also showing which block 20+ mining pools are mining on.
Will start a livestream later!
Planning to cover the start of the mandatory signaling in 1500 blocks on fork.observer/mainnet. Will run a Bitcoin Core node and a BIP-11O node to show the (potential) split.

It turns out new top level domains (.com, .org, .xyz) get issued rarely, and there is a new application window to apply for new ones which ends very shortly - a matter of days, 12th Aug is the deadline.
It appears likely that the ".bitcoin" domain will be auctioned off to the highest bidder unless a "community priority application" is submitted which can demonstrate "support from the identified community".
It's a tall ask, we bitcoiners rarely agree on things, but we all want to minimise the risk of ".bitcoin" immediately falling into the "wrong" hands (e.g. people who want to see bitcoin fail).
Seeing no other community priority application, wiz is making such an application and proposes that a committee of bitcoiners make the key decisions around domain assignment rather than a single corporate entity. The role of this committee is tightly scoped just to the .bitcoin domain management, mitigating any risk of scope creep / over-representation.
Have a read, if you support this please consider making a statement of support in the format described.

📢 AN ALLE DEUTSCHEN PLEBS 📢
Der Verlust der Bitcoin-Haltefrist droht.
Die Petition zum Erhalt ist jetzt online. Damit sie öffentlich im Petitionsausschuss des Bundestages behandelt wird, brauchen wir innerhalb von 6 Wochen mindestens 30.000 Mitzeichnungen.
Es geht darum, dass langfristiges Sparen in Bitcoin in Deutschland nicht steuerlich bestraft wird.
Was jetzt zählt:
✅ Petition unterzeichnen
✅ Teile diesen Post und mache andere Bitcoiner darauf aufmerksam!

For one year all mining rewards from the miner I won will go to the Frankfurt #Bitcoin meetup @BTCFFM.

I won first prize in the Satoshi Millionaire Quiz at #BTCLändle this weekend.
A S19k Pro 120TH miner from @MiningMunich.
@Anne47003228 supported me technically and mentally.
Thanks a lot for that! Team AnonymousA🚀
I would like to donate the entire mining proceeds (profit after costs) of the 1st year to a good #Bitcoin cause.
Now I need suggestions from you all.

All newer Coinkite models affected.
If you are a user of their products - get active on mitigation measures TODAY.
Do not panic - but do not wait neither to become active.
Coinkite has now confirmed the entropy bug also impacts Mk4, Mk5, and Q models. Seeds generated on a Mk3 are severely affected; seeds generated on a Mk4, Mk5, or Q are also weakened, though harder to crack.
Our recommendation: if any key in your wallet or multisig quorum came from a seed generated on a Coldcard (without dice rolls or a passphrase), replace that key and migrate funds to a new wallet. You can generate the new seed on a different vendor’s hardware, or continue with Coldcard: update to the fixed firmware first (v5.6.0+ for Mk4/Mk5, v1.5.0Q for Q), and consider the dice-roll import method (100+ rolls) for verifiable entropy.
While you prepare to migrate: if you have coins on an address you’ve previously spent from, move them to a fresh address right away. Spending reveals an address’s pubkeys on-chain, letting attackers match cracked seeds against them directly. Fresh addresses don’t have this exposure.
For our paid users: some of the platform keys used in assisted wallets were generated with a Coldcard Mk4. The platform key alone can never move funds — it sits below your wallet’s spending threshold by design — and all new assisted wallets now use platform keys not generated by Coldcard, with full 256 bits of entropy. If you also use Coldcard for your own keys without a passphrase or dice rolls, replace those keys as soon as possible. If you don’t use Coldcard, we still recommend migrating to a new wallet at your convenience, as a cautionary measure.
If you have an active assisted wallet, we’ve given you one extra assisted wallet so you can set up a new quorum and migrate your funds at no additional cost. Details in the email we’ve sent to subscribers, or reach us via in-app Chat Support.
Major security incident involving Coldcard Mk3 - situation still developing.
1) Do not panic
2) ...but if you are a CC user, read up carefully on the situation and launch immediate mitigation efforts.
This is not a drill. 🚨
COLDCARD Mk3 Security Advisory
If you generated a seed on a Mk3 after firmware 4.0.1, your funds may be at risk.
Mk4, Q and Mk5 are not affected based on our early analysis.
Read the advisory and migrate carefully:
