My favorite (childhood) ponzi scheme just imploded.
I felt bad for missing out on all the returns.

But it turns out, the marketcap was mostly the bezzel.
Follow me for more fringe ponzi scheme investing content.

If you were wondering, these weapon skins are not functional and just a "flex", just like so many real life things.

Anyone else find Swiss public transport pricing unnecessarily complicated?

- GA Travelcard (simple but CHF 4,000)
- Point-to-point travelcards
- Half Fare Plus with the prepaid reload discounts
- Or sticking with regular Half Fare Travelcard

simple solution:

@nonzerosumjames.bsky.social Hey, do you by chance have a blogpost or podcast episode on effective altruism or similar?

CSGO/CS2 investing - exhibit 1

In late October '23 I bought this arguably good looking, but objectively very rare skin from a friend for 50 CHF.

In March '25 sold the item sucessfully on csfloat (skin for cash platform), but stupidly missed the notification email.

The transaction was cancelled.

Can you help me understand "MPH Health Care AG" (93M1.F)
-> 100M mcap, 300m NAV

Is this possible, is the complicated holding structure here a possibility to inflate NAV values?

Thank you for your time

Creating a 14bn€ revenue milk/cheese giant (unlisted)

Decent writeup of T-Mobile

But, lack of valuation, shareholder structure.
Not a unique idea yet, needs a compelling story!

Try to cohesively explain, why the company is misunderstood by the market, how is FCF-yield comparing to comps?

And as always:
WHAT ARE THE CATALYSTS?

Q: "Can we pay 75m in annual interest?"

A: "Don't worry, we have 400m in revenue, which is cashflow adjacent!“
