MiCAR applies in full across the EU from 1 July 2026. After that date, an EU crypto-asset service provider operating without a MiCAR licence is in breach of EU law. For Bitcoin holders, MiCAR sets a baseline: segregated client assets, minimum own funds, and supervised providers. What MiCAR means for your Bitcoin: nitter.net/blockrise/status/20668…

RT @HansDiederen: Exciting times in ₿ city Arnhem at @onthebrinkie @NoderunnersNET Noderunners conference 2026 ₿ 🧡

Mad props to @NoderunnersNET for pulling off yet another great conference. The fact these guys do this with nothing but passion is just remarkable. Can’t wait for the next one 🧡

Bitcoin transactions spend existing outputs and create new ones. That UTXO model shapes fee management, reconciliation and privacy. Treasury policy should account for transaction structure, not only account balances.

A valid Bitcoin transaction can remain unconfirmed until a miner includes it in a block. That distinction matters for operations: broadcast, mempool acceptance and confirmation are separate states and should be monitored separately.

MiCA defines custody broadly: safeguarding or controlling clients’ bitcoin or the means of access to it. The operating model still matters. Clients should understand ownership records, access, liability and return procedures.

At 2% annual inflation, €10,000 in cash has about €8,200 of purchasing power after ten years if it earns nothing. Inflation pushes savers towards risk just to stand still. Bitcoin offers a different rule: fixed issuance. Bitcoin Weekly with @jos_lazet: piped.video/YB2jixEIoQs

Every bitcoin custody model should answer three questions clearly: who can authorise a transaction, what happens when a key is unavailable, and which controls apply during recovery. Key storage alone is not the full design.

A Bitcoin transaction fee pays for scarce block space, not for the amount transferred. Good treasury operations manage UTXOs, timing and fee policy together. A large transfer does not inherently require a proportionally larger network fee.

Proof of reserves can provide evidence about assets at a point in time. It does not automatically establish complete liabilities, asset control or solvency. Its scope, methodology and independence matter as much as the headline result.

Bitcoin's issuance follows rules that nodes can verify independently. The block subsidy halves every 210,000 blocks, while transaction fees remain part of the miner reward. Monetary predictability comes from validation, not discretion.

Multisignature can distribute authority across several keys, but the threshold alone is not a control framework. Key independence, signer identity, recovery design and change procedures determine whether the setup reduces concentration risk.

An on-chain address can show where bitcoin moved. It cannot, by itself, show who can authorise a transaction, how keys are protected or how recovery works. Custody review needs blockchain evidence and operational controls.

Bitcoin settlement is not a binary event. Each additional valid block adds proof of work above a transaction, making a competing history progressively harder to produce. Confirmation policy should reflect transaction value and operational risk.

Custody fees should pay for a service, not rise simply because the bitcoin price rises. Holding bitcoin with Blockrise costs 0% per year.

A backup protects against loss. It does not protect against a compromised key. Good custody separates key generation, storage, authorisation and recovery instead of treating them as one problem.

Bitcoin's fixed supply gets the attention. Its verifiability is just as important. Anyone can inspect the rules, audit the ledger and verify that no administrator changed the terms.

Galaxy says Coldcard attackers likely used uncensored AI models. Days later, Boltz went offline because AI attacks outpaced its patches. The protocol itself did not move. New Bitcoin Weekly with @jos_lazet: piped.video/3TI3BU4L2Vw

If you could verify one thing about how your bitcoin is held, what would matter most: where it sits on-chain, who controls the keys, or how recovery works?
