You can start with as little as $5 to $10 on most exchanges. Here is the real minimum, why very small buys waste money on fees, and how much a beginner should actually put in.
You do not need much. Most large exchanges let you buy crypto with as little as $5 to $10, and a few let you start with $1. There is no rule that you must buy a whole coin. The real question is not the minimum, it is how much you should put in and how to keep fees from eating a small buy.
This guide covers the true minimums by payment method, the point where small buys stop making sense, and a simple way to size your first purchase.
Two things decide how little you can buy: the order size the exchange allows, and how divisible the coin is. The coin price is almost never the blocker.
Bitcoin splits into 100 million units called satoshis, so a $10 buy simply gets you a fraction of a coin. We cover that in detail in can you buy less than one Bitcoin.
Just because you can buy $5 of crypto does not mean you should. Fees are charged as a percentage or a flat amount, and on a tiny buy they take a painful share of your money.
Put $10 on a card at a 2% fee and a 1% spread and about $0.30 is gone before the price even moves. Move that same $10 to your own wallet later and a network fee can take another dollar or two. On $10 that is a heavy start. On $100 the same costs barely register.
A practical floor for a first buy is around $50 to $100. That is large enough that fees become a rounding error, and small enough that a beginner mistake will not hurt.
A common rule among financial advisers is to keep crypto to a small slice of your savings, often no more than 5 percent, and to only use money you could lose without changing your life.
Most consumer finance guides, including this Yahoo Finance walkthrough, land on the same advice: start small, automate, and never bet the rent.
