What is Dopamine?
The Jstin Trading Journal is a set of Justin's own notes from trading crypto. He uses it to record his trades, the ones that went wrong as well as the ones that went right, along with thoughts on mindset, key pieces of information and loose discussion of whatever trading topics come up. Members read the journal through a private Telegram group, and the membership also includes a course area on Whop.
Justin, who goes by jstin on Whop, opened the store in July 2025 under the Dopamine name, and the product headline calls it the Dopamine Traders Group. His biography says he enjoys building brands and businesses online and trades alongside that, and that he has chased new trends since college, with interests ranging over esports, sneaker reselling, blockchain and early-stage investing.
Who it suits
- Crypto traders who read Chinese
- Readers who want to see another trader's mistakes
- People curious about trading mindset and process
- Traders who prefer a yearly plan to monthly billing
Why the Dopamine journal is paid
In the store's FAQ, Justin explains that the journal began as private notes meant to keep him alert to his own mistakes, and that it also captures information from skilled traders around him. He says he chose to charge for it so it reaches people who genuinely enjoy the material and want to learn and grow alongside him.
How Dopamine billing works
The Jstin Trading Journal is the store's only product. It renews every 365 days as a recurring Whop membership, so a single payment covers a full year of access to the Telegram group and the course area before the next renewal.
