Ethereum (ETH) is not considered a "sister" of Bitcoin — it is more like an entire different family, founded with a completely different purpose.

📌 Why is ETH not sister to BTC?

Because:

It did not originate from Bitcoin's code

It is not a fork of Bitcoin

It was not created to be just a currency

BTC was born to be decentralized digital money.

ETH was born to be a global platform for smart contracts and decentralized applications (dApps).

📘 Correct relationship between BTC and ETH

The most accepted comparison in the market is:

Bitcoin = Digital gold (store of value)

Ethereum = Global computer (smart contracts)

They coexist, but follow completely different missions.

🌱 Want a parallel?

If BTC were a precious metal,

ETH would be electricity — not a sister, but something that changes the entire system in another way.
