Crypto prices

The section shows six cryptocurrencies, one per card: the logo, the name, the symbol, the price in dollars, the 24-hour change in green when it goes up and in red when it goes down, and the curve of the last seven days. An RSI badge completes the line, computed on the spot from those same points. The section refreshes itself every minute, and a button forces the update without waiting for the next round.

You have no price to enter and none to keep up to date, the prices coming from CoinGecko with no account and no key to provide. And the section is written for the bad days as much as the good ones: if a refresh fails, the last prices stay on screen with a note saying so, rather than an empty page; if a single coin is missing, its line says so and the other five carry on; if the request drags, it is dropped after twelve seconds. When your user comes back to the section after leaving it, it catches up on the refresh it missed.

A specialist outlet, a community, a training organization: wherever the price of the day is part of the conversation, it has no reason to live anywhere else. This is the question your user was about to go check outside, and it now finds its answer with you.
