§Spot Bitcoin ETF

Definition:
A fund that lets people invest in Bitcoin through the stock market, without directly owning it.

Example:
Instead of buying Bitcoin yourself, you buy shares of a fund that holds Bitcoin for you.

Post angle:

A Spot Bitcoin ETF lets institutions buy Bitcoin without touching Bitcoin, but the price still moves because the fund is buying real Bitcoin behind the scenes.

§Private Keys vs Seed Phrase

Definition:

• Private key = access to your Bitcoin

• Seed phrase = backup that generates all your private keys

Example:
Your seed phrase is like a master password that can recover your entire wallet.

Post angle:

Your seed phrase is your Bitcoin. Lose it = everything’s gone. No reset button.

§Self-Custody

Definition:
Holding your own Bitcoin using your own wallet and private keys (no third party).

Example:
Using a hardware wallet instead of leaving your Bitcoin on Coinbase.

Post angle:

If an exchange goes down, self-custody users are fine. Everyone else is stuck waiting.

§Lightning Network ⚡

Definition:
A faster, cheaper layer built on top of Bitcoin for instant payments.

Example:
Sending someone $2 instantly with almost no fees.

Post angle:

Lightning turns Bitcoin from “digital gold” into actual usable money.

§UTXOs

Definition:
Small chunks of Bitcoin in your wallet that come from past transactions.

Example:
If someone sends you $10 twice, you now have two separate “pieces” of Bitcoin.

Post angle:

Your Bitcoin wallet isn’t one balance—it’s a collection of pieces being combined when you spend.

§On-chain vs Off-chain

Definition:

• On-chain = recorded on Bitcoin’s blockchain

• Off-chain = handled outside it (like Lightning)

Example:
Buying a coffee via Lightning (off-chain) vs sending BTC directly (on-chain).

Post angle:

On-chain = secure but slower.
Off-chain = fast but relies on layers like Lightning.

§Hash Rate

Definition:
The total computing power securing the Bitcoin network.

Example:
More miners joining = higher hash rate = harder to attack Bitcoin.

Post angle:

Rising hash rate means Bitcoin is becoming more secure, not just more popular.

§Halving

Definition:
An event every 4 years where new Bitcoin supply gets cut in half.

Example:
Miners used to earn 6.25 BTC per block → now 3.125 BTC.

Post angle:

The halving doesn’t pump price instantly—it slowly reduces new supply over time.

§Bitcoin Dominance

Definition:
Bitcoin’s share of the total crypto market.

Example:
If Bitcoin dominance is 55%, it holds 55% of the entire crypto market value.

Post angle:

When dominance rises, money is flowing into Bitcoin, not altcoins.

§Layer 2’s on Bitcoin

Definition:
Technologies built on top of Bitcoin to improve speed and scalability.

Example:
Lightning Network is a Layer 2.

Post angle:

Bitcoin doesn’t scale by changing its base layer, it scales by building on top of it.
