About

A few links, referrals, and tip jars.

§Crypto exchanges

Kraken.com is the exchange I generally use for larger transactions and for placing limit buy/sells at specific price levels when I need to be careful. They're a long-time exchange and very reliable. By verifying and funding your account with $200 and trading $200, we both get $75 within two weeks of completing that requirement. You can immediately withdraw it after that — it is not a casino.

I recommend not gambling though; it tends to not go well in the end.

§Prediction markets

Manifold Markets is a play-money prediction market with a varied range of interesting, often un-serious topics. It has a wonderfully endearing community and loses some of the arrogance of real-money markets. They did an experiment with sweeps laws but it failed miserably (although I was in profit there). I get 1000 coins if you sign up with the link, and no purchase is required — only that you make a trade. There's no way to make money there, but it's an interesting place to test ML algo trading and similar.

§NanoGPT

NanoGPT is a router for generative AI models with a focus on privacy — though you should always be careful about your data with any middleman involved. It supports cryptocurrency payments and pay-per-use pricing, which is very useful for small-scale projects. It's a good fit for more complicated tasks that need flexible model selection rather than a simple wrapper or chat frontend, and it has that too. You can even try special-access models like GPT 5.3 Codex.

Each invite below has some free unconditional credit attached. Please only take one!

If you'd rather use a referral with no attached credit, this one is fine too: nano-gpt.com/invite/xBDKCdm3. I get commission if you continue to use the service with the same account. Last updated 2026-04-30.
