Crypto exchange.
In plain English
A crypto exchange is an online marketplace that matches buyers and sellers of cryptocurrencies and converts between crypto and regular money. Most people first buy crypto on one. Exchanges charge fees, often a percentage of each trade plus a spread between the buy and sell price, and those costs add up with frequent trading. Many exchanges also hold your coins for you, which is convenient but means you are trusting the platform to stay solvent and secure, as several failed exchanges have shown. Exchanges are not banks, and account balances are generally not federally insured.
01Why it matters
The exchange you use sets your trading costs and, if it holds your coins, controls your access to them, so its fees and financial health directly affect your money.
02The math, step by step
Suppose an exchange charges 1.5 percent to buy and another 1.5 percent to sell. One 10,000 dollar round trip is about 300 dollars in fees. At a 7 percent long-run return, 300 dollars a year would grow to roughly 28,000 dollars over 30 years.
03What this is NOT
A crypto exchange is NOT a bank. Balances are generally not FDIC or SIPC insured, and if the platform fails, recovering your funds can be slow, partial, or impossible.
