Hot Wallet vs Cold Wallet: Which Do You Actually Need?
The distinction is simply whether the private key touches an internet-connected device. Everything else follows from that.
The single difference that matters
A hot wallet keeps its private key on a device that connects to the internet — a phone or browser extension. That is convenient and it means the key exists somewhere reachable by malware, a malicious signature request, or a compromised device.
A cold wallet keeps the key on a device that never exposes it. Transactions are signed on the device itself and only the signed result leaves it, so a compromised computer can display a wrong transaction but cannot extract the key.
The allocation most people should use
Use both, split by purpose. A hot wallet holds what you actively use — an amount you would be annoyed but not damaged to lose. Cold storage holds savings, the portion whose loss would genuinely matter.
The threshold is personal, but the framing is not: any amount you are not willing to lose to a single mistaken signature should not be in a hot wallet, because that is the exact failure mode.
What both share, and what actually kills people
Both are only as safe as the recovery phrase. A hardware wallet with the phrase photographed and stored in cloud backup provides roughly the security of a hot wallet, because the phrase is the asset and the device is only its guardian.
Write it on paper or metal, store it physically, never photograph it, never type it into anything other than the wallet device. And use a read-only tracker to watch balances — monitoring requires only a public address, so there is never a reason to expose a key just to see a number.

Frequently asked questions
Does this apply to stocks and commodities too?
The method does; the numbers do not. Levels, sizing and deciding in advance work identically across asset classes, but thresholds must be recalibrated — equities gap around earnings and only move during market hours, commodities trend more slowly, and currency pairs move a fraction of what crypto does, so a 1% move there is significant.
