Does a bitcoin wallet actually store the coins?

No, a wallet does not hold bitcoin directly. It holds a cryptographic signature created from your passphrase that enables you to control your bitcoin on the network.

Why is the supply of bitcoin capped?

The total supply is capped at 21 million coins. This makes it deflationary and prevents the debasement that can happen when money is printed.

How are bitcoin transactions secured?

Transactions are secured by math and energy through proof of work. The more confirmations a transaction has, the more energy an attacker would need to reverse it.

Is bitcoin practical for everyday purchases?

Critics argue it is impractical as an everyday currency because the network can be slow and the value is volatile, though some appreciate its low transfer fees compared to traditional banking.

How Bitcoin Works Ledger Supply and Transactions Explained

Bitcoin operates as a decentralized peer-to-peer electronic cash system and a neutral store of value, working without intermediaries like banks or governments.

The network relies on an immutable ledger tracking a fixed supply of 21 million coins, preventing debasement. Wallets do not hold the coins directly, but store cryptographic signatures that control your bitcoin on the network.

Transactions are secured by proof of work, meaning the more confirmations a transaction has, the more energy an attacker would need to reverse it. While some users value it as a way to transfer value with low fees, others find it useless as a currency due to slow network speeds and high volatility.

Bitcoin functions as a decentralized, peer-to-peer electronic cash system and a neutral store of value, designed to operate without the need for intermediaries like banks or governments.

Core Principles of Bitcoin

Immutable Ledger: Bitcoin is a ledger that tracks a fixed supply asset, ensuring every transaction is recorded and cannot be altered. "Bitcoin is a ledger. That’s it."

Fixed Supply: The total supply of Bitcoin is capped at 21 million coins, which makes it deflationary and prevents debasement through printing. "It’ll always be 21mil in supply. Can’t inflate. Open source. Trusted."

Permissionless and Trustless: Bitcoin allows anyone to transact without needing permission from a central authority, relying instead on mathematical rules and incentives for security. "You don’t need to trust a middleman to hold your money or approve your transactions."

Transaction Mechanisms

Wallets and Keys: Bitcoin wallets don't "hold" Bitcoin directly; rather, they hold cryptographic signatures (keys/passphrases) that grant control over your Bitcoin on the network. "Correct, wallets don't "hold" bitcoin, just a cryptographic signature that was created from your passphrase (password); this passphrase is what enables you to control your sats - held in a wallet - on the bitcoin network."

Proof of Work: Bitcoin is secured by "math and energy," where the more confirmations a transaction has, the more energy an attacker would need to reverse it. "The more confirmations you wait for, the more insane the amount of energy an attacker would need to reverse your transaction."

Transaction Speed: The network can be slow for transactions, leading some Users to state it's "useless as a currency since the network is slow."

Use Cases and Criticisms

Store of Value: Many Users view Bitcoin primarily as a store of value due to its fixed supply and resistance to inflation. "Its an immutable ledger that can be transported across sovereign borders in the confines of a human mind, which tracks a fixed supply asset in a world of endless debasement."

Alternative to Fiat: Bitcoin offers a way to transfer value without reliance on traditional banking systems, which can involve high fees and long settlement times. "With bitcoin, they received payment in a few minutes and the fee’s were a fraction of that."

Volatility and Practicality: Critics point out that Bitcoin's high volatility makes it impractical as a currency for everyday purchases. "It's neither investment grade nor a currency."
