Will there be Proof of reserves
Can you weigh in on where the BTC will be held? Huge chance to differentiate vs MSTR. Self custody and proof of reserves!
21mil coins is not enough. Let's make some brilliant ideas, fresh, new...

Glad to have you in the space ππΏ
Yo Jack,
I sold 10% of my MSTR to buy XXI
Hopefully you outperform mstr

That video was all hype about it being a Bitcoin only company and no real substance about what you actually do. Just a few vague statements about financial services or education. I do not trust a SPAC much either, they tend to be pump and dumps.
Will you have proof of reserve? And is bitcoin in self custody?
When will XXI be the ticker ?

example:
π Today weβre supporting @Andreas Griffin
from Bitcoin-Safe.Org with 1,000,000 satoshis for his work on Bitcoin Safe β a beginner-friendly multisig wallet for Mac, Windows, Linux, or anywhere Python runs. Why this matters π§΅π
π§ Development of Specter Desktop is no longer a priority at Swan. A vital open-source wallet has essentially become abandonware β leaving a painful gap in the Bitcoin ecosystem.
π‘ Andreas, a former Specter developer himself, recognized this gap β and with Bitcoin Safe created a brand-new solution that already goes beyond what Specter offered.
π What makes Bitcoin Safe special:
An open-source wallet focused on multisig and hardware wallet integration. It combines the strengths of Electrum, Specter, and @mempool β with Nostr functionality added in.
π§ The beginner-friendly multisig wizard makes secure Bitcoin self-custody accessible β even for non-technical users.
πΌοΈ The graphical transaction display isnβt just functional, itβs beautiful. Even better than Sparrow! For Bitcoin artists like Fractal_Encrypt and @Kanuto it can be exported as vector graphics.
π But the real gamechanger is the Nostr integration β enabling secure, decentralized PSBT exchange between cosigners.
π Itβs comparable to Electrumβs Cosigner Pool or nunchuk's proprietary chat β but here: fully open source, set up in seconds, and run via encrypted Nostr DMs.
π Not just PSBTs β UTXO labels can be shared via Nostr too. A key building block for collaboration in multisig setups.
π Weβd love to see other wallet clients adopt this Nostr sync functionality as well β to increase client diversity, especially for organizations with varying needs.
π οΈ Bitcoin Safe delivers this critical workflow entirely open source β built on the decentralized Nostr protocol. A milestone for sovereignty in the Bitcoin ecosystem.
π€ Open-source Bitcoin projects are chronically underfunded. Thatβs why itβs so important to support developers like Andreas who push boundaries and define new standards. Bitcoin Safe πͺ
π£ Our support of 1,000,000 satoshis is meant to send a message:
High-quality open-source development deserves funding.
2 out of 5 cosigners signed this transaction using Bitcoin Safe. Whoβs next?
π± Follow @Andreas Griffin and check out the project.
Join the Einundzwanzig Association and suggest other projects worth funding.
Open source stays alive β with your help.

Never thought Iβd be skeptical of JM. Please prove it unfounded.
BPS sounds great, but how can you acquire more Bitcoin than you purchase? What is the business model?
transaction id or it didnβt happen
Saylor proved the playbook works
Demand for BTC financial products is HUGE
Institutional capital is slowly realizing they need exposure beyond TradFi
Or at least they want in on these returns
Trillions of $ are coming for BTC/equity-related companies
This is just the start
Maller's tweeted, "We plan to provide proof of reserves"
If they do, $MSTR might be forced to do the same
Congrats @jack mallers
The best money in the world will continue to be adopted in every shape and form
There is no second best. #bitcoin

Who knew one of my favorite songs from the 1990s, was hinting at a future of @jack mallers and #XXI
