There's definitely an open question right now about how much the advancements in technology should affect the valuation levels investors consider reasonable for the market overall

Good bets become bad bets when they become popular bets.

Applies to:
renting vs. owning
quality businesses vs. cigar butts
blitzscaling vs. profitability for Startups & VCs

Right now:
Owning real estate is over-hyped
Buying quality businesses is over-hyped
Profitability is over-hyped by NYC VCs

Even more true today than it was when I wrote it.

Kind of insane that crypto prices are down way more than retail stocks, considering that retail stocks are directly affected by the tariffs and cryptocurrencies aren't.

In other words:
Beginner: I just want my code to work
Intermediate: I want my code to tell me if it fails
Advanced: I want to prevent failures in the future
Expert: I just want the error messages to be at least a little understandable

Web 3 is the Biggest Network Effect in History.

Why is it taking so long for web 3 to reach full product-market fit?

Because web 3 is the biggest network effect in history

Network effects start slow

And the bigger they are, the slower they start

Ethereum has intrinsic value in the same way that the USD does

There are certain (digital) goods and services that you cannot buy without it

ETH is money.

I have been writing code examples of how to make an HTTP request in 20 different programming languages for our crypto price API.

I might increase that to 50 examples if I decide to write examples for popular frameworks in those languages as well.

$2.5B/year paid out to validators. $ETH has intrinsic value. No question. People can debate how much, but to claim there's no intrinsic value would just be announcing that you don't know the numbers.

One of the great frustrations of software engineering may be building tools for yourself that you don't use, but one of the great joys of software engineering is building tools for yourself that you do use.

I waited until the last possible second to register my business as an LLC, because I wanted to do all of the things that actually matter first:

- Learning what makes a good idea vs. bad
- Learning how to build software
- Building our software

cs finance is now a registered LLC!

I've had a lot of startup ideas before, but this is the first one I've ever formed a business entity for officially.

Why wait until now to do it?

Because it's fun.

That's one of the reasons I got into entrepreneurship in the first place, and I clicked back into that other gear and now I'm having a blast writing this post for tomorrow before I run out to the post office in the rain and run back to make a dozen phone calls before places close up.

But then I remembered: Wait, I love being busy.

One of the cool things about figuring out what you want to do and then doing it is that as it gets hard, you start to rediscover all of the things about yourself that drew you to it in the first place.

Like at first when I started getting really busy the last couple weeks, I was very stressed out.

10.12.2024 17:34 ๐Ÿ‘ 0 ๐Ÿ” 0 ๐Ÿ’ฌ 1 ๐Ÿ“Œ 0

Things are getting busy.

Lately, my business has gone from a marathon of despair to a sprint of trying to keep up.

But there's a silver lining:

Software Startup, Perception vs. Reality:

Perception:
50% Building Software
50% 'The Business Side'

Reality:
75% Learning How to Build Software
20% Building Software
5% 'The Business Side'

I own crypto. We can support quality projects and reject scams at the same time without blaming the users.
