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.

Next week is going to be pretty special!
Not only does Plan B Week kick off, packed with Bitcoin events, but we’ll also have not one but TWO Satoshi Spritz in the same week 🤯
Our usual one on Monday, back at Proof of Steak, where they’ve promised us a dedicated deal here too: drink + focaccia for 21 CHF 👌
And on top of that, the Satoshi Spritz Speciale, the biggest one of the year, on Thursday, the evening before the Plan B Forum! Huge thanks to our sponsors who are making it possible: @Blockstream, @Braiins, @blockrise and @terminus_events 🧡

You can’t miss either of them, but for now, if you’re planning to come on Monday, here the details... 🙏
📅 Monday, October 19
🕕 From 6:30 PM
📍 Proof of Steak, Contrada di Sassello 10

Blockrise is a finalist of @cypher_tank 2026. On 27 October, our CEO @Jos_Lazet pitches in Lugano to very seasoned judges. The story: Bitcoin custody at the core, with financial services built around it. Bitcoin only, from the Netherlands. Bitcoin ownership for everyone 🧡

Joining the custody panel at Capital Sessions, 21 October in Lugano:
@Rob1Ham, CEO of @AnchorWatch: Bitcoin custody and insurance, backed by Lloyd's of London.
@jos_lazet, CEO of @blockrise: MiCAR-licensed Bitcoin custody and Bitcoin-backed loans.
More announcements coming!
Blockrise publishes part two of "Getting off zero": what changes when a bitcoin allocation is managed by rule, not held passively. Backtest 2017 to mid-2026, net of costs.

Past performance does not guarantee future returns.
Our CEO @jos_lazet created an introduction about our platform, check it out! 👇
While at @btchelevent drinks, I asked Opus 5.5 to generate a killer introduction to @blockrise. Literally a single shot, I’m impressed..

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 🧡
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:

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.
