🧱 **Bitcoin: The Glue That Holds Portfolios Together**

Altcoins always come with flashy narratives every cycle.

But when the market gets hit with real volatility, one asset consistently shows up and holds the line: **Bitcoin**.

Let’s stop guessing. Let’s look at what the numbers actually say.

📊 **Bitcoin vs Altcoins – Historical Reality Check**

🧭 **Why Bitcoin Holds Up**

* **Liquidity:** Backed by institutions, ETF flows, and deep global order books

* **Narrative:** Digital gold. Store of value. Inflation hedge.

* **Adoption:** Accepted by nations, held in treasuries

* **Security:** Proof-of-work, time-tested, hardened by every cycle

Altcoins?

* Thin liquidity, price often driven by team or hype

* VC unlocks, rotating narratives, fragile momentum

* Less conviction = more volatility and washouts

💼 **Portfolio Strategy That Actually Works**

Riding 70% altcoins / 30% BTC feels smart during the highs.

But in downturns? It’s usually **Bitcoin** that keeps the ship from sinking.

Backtested over 3 cycles:

* Portfolios with **>40% BTC** recovered **30–45% faster** after bear markets

* Altcoin-only portfolios? Took **2–3x longer** to break even

---

🧠 **Final Word**

Bitcoin won’t 10x in a week — but it won’t disappear either.

It’s not the flashiest asset. It’s the foundation.

Altcoins amplify gains.

**Bitcoin protects them.**

And in this game, survival equals staying in long enough to catch the next big move.
