Fact: Ethereum was originally crowdfunded through an ICO in 2014 that raised $18 million

I need to write 100-140 words total, starting with "Did you know?" and expanding with 2-3 context sentences.

Let me draft:

"Did you know? Ethereum was originally crowdfunded through an ICO in 2014 that raised $18 million — a modest sum compared to today's billion-dollar token sales.

Vitalik Buterin and the founding team used these funds to build the decentralized world computer we know today, launching the network in July 2015.

- Final line: "#Trading #CryptoTrading #CryptoFact #LearnCrypto" exactly (presumably with spaces between hashtags). Must be the last line.
- The final line must contain those hashtags, presumably separated by spaces.

We need to produce a "Did You Know?" post on Binance Square. No markdown, just plain text.

- First line: "Did you know?" (that's 3 words? Actually "Did" "you" "know?" counts as three words? "know?" is a word. So 3 words.)

Then we expand with 2-3 sentences. Provide context: e.g., "Ethereum was originally crowdfunded through an ICO in 2014 that raised $18 million, making it one of the
