Aladin7x/soi-gia-btc-plugin — reverse-engineered prompt

Build me a simple plugin around Bitcoin trading. I want something a normal user can open and quickly see the current BTC price, recent movement, and a clear read on whether the market looks strong or weak right now. Let me switch between a few time ranges, refresh the data, and keep a small area for notes about planned entries and exits.

If real trading support makes sense, start with a safe paper trading mode first so I can simulate buying and selling BTC and see profit and loss without risking money. If full trading is too much for a first pass, focus on price tracking and trade planning.

Please keep the interface clean, simple, and beginner friendly. Make it feel useful right away, not cluttered. Add basic handling for failed or missing market data, and make sure it is easy to run locally. If the repo is too bare to infer details, keep the first version practical and focused, and look up current docs online if you need to.
