The user wants a Binance Square post. Requirements:

- No markdown (so plain text, no formatting)
- Start with: "Did you know?"
- 100-140 words total
- Expand the fact with 2-3 interesting context sentences
- End with a surprised reaction emoji written out as text (e.g., "Mind blown!") and a question
- Final line: "#BullRun #HODL #CryptoFact #LearnCrypto"

Structure:

Then final line with hashtags.

Make sure no markdown (no bold, italics). Just plain text.
