Rankin/Bass – That nostalgic stop-motion look like Rudolph the Red-Nosed Reindeer. Cozy and janky.

The US Crypto Reserve is NOT the government speculating on crypto tokens

The US also has foreign currency reserves

And commodity reserves

They do this w/ important global assets to hedge against large price fluctuations (to ensure the economy can function in short term changes)

The US isn’t buying random crypto tokens as investments. They are buying specific L1 tokens, which are seen as commodities

If blockchains become an integral part of the financial system and how global trade/commerce works, then L1 tokens have importance as gas/utility to use these technologies

The US is simply building a reserve of assets for when that world becomes a reality

So no, the US won’t be buying tokens that represent businesses/apps

And no the US likely won’t be buying tech stocks either (unless it makes sense for data or other commodity like reasons)

They are preparing for a world where everything is done onchain. Currently, we don’t know what chain that will exist on.

Which is why they will probably hold a basket of L1 tokens, even random ones like ADA, though I imagine this is being done moreso to promote American made blockchains

Don’t confuse a reserve with the US speculating on random crypto tokens. There is a method to their madness.

@Codie_Sanchez What would you have to say for the opposite-people thinking they can but never manage to build something profitable?

[Jean de La Rochebrochard @2lr]

Until you're 10+ in a startup , the only roles that exist are head of get shit done & chief common fucking sense officer.

[Codie Sanchez @Codie_Sanchez]

An entire generation has been misled about startups and wealth.

• New business failure rate: over 65%
• Acquisitions failure rate: under 20%

Opportunity's here. But you might miss it..

How to decrease your chance of failure buying a business (The 3 M’s of Risk):

[Tetch.jar @jarvistatch]

@Codie_Sanchez It’s absolutely brilliant. For recurrent and predictable tasks it’s straightforward. But how would you approach this for more one-off tasks ?

For example building an MVP or software dev tasks.

Clear writing and clear speaking are simply outputs of clear thinking.

I've tried all (24) AI coding agents & IDEs 😵‍💫

[Cursor, Softgen, Windsurf, Wrapifai, Copilot, Lovable, Bolt, v0, Replit, MarsX, Claude, AmazonQ, Pear, Devin, Github Spark, IDX, Webdraw, Tempo, Cline, Continue, Databutton, Base44, Qodo, Aider]

The Vibe Coding giga-thread:

[neural nets. @cneuralnetwork]

releasing the DeepSeek R1 blog, which explains the whole paper in great detail, not excluding any math, but anyone with basic class 12 math knowledge can understand it (link in replies)

do share and rt :)

@devfolio AI agent to find early adopters.

AI agent to write the presentation page based on actual code.

AI agent to deploy all the boilerplate with the hackaton sponsors’ tech stack

[Devfolio @devfolio]

If Devfolio built an AI agent for hackathons, what would you want it to help with?

Share your wishlist, no idea is too wild.
