How Much Capital Do You Need for Crypto Arbitrage?

How much capital do you need for crypto arbitrage? Less than the gurus imply, more than the "start with $50" crowd admits. The honest answer is that capital requirements are set almost entirely by fees: every strategy has fixed and percentage costs, and your account must be big enough that a realistic spread leaves meaningful profit after all of them. This article does that math for each major strategy.

Fees Set the Floor

Consider a typical cross-exchange trade: 0.1% taker fee on each side (0.2% round trip), plus a flat network withdrawal fee of a few dollars. On a $100 trade capturing a 0.5% spread, the gross gain is $0.50 — already less than the $0.20 in trading fees, and the flat withdrawal fee wipes out the rest several times over. The same trade with $5,000 of capital yields $25 gross against roughly $10 in percentage fees plus the same few dollars flat — suddenly viable.

This is the fundamental scaling law of arbitrage: percentage costs stay constant, but flat costs shrink as a share of larger trades. Small accounts are not just disadvantaged — below a certain size, the math literally cannot work. The break-even point is where your expected net edge per trade comfortably exceeds the sum of all flat fees, with margin for the trades that go wrong.

Minimum Viable Capital by Strategy

These are practical minimums for learning with real money, not theoretical ones — and "practical" means you can survive a few losing trades without the account becoming untradeable. Notice that the cheapest strategies to learn are triangular arbitrage (no transfers) and manual cross-exchange on major pairs. The fee math walkthrough shows exactly how to compute your own break-even.

The Costs Beginners Forget to Budget

Trading capital is only part of the budget. Beginners routinely forget: spread across venues — concurrent strategies need funds on every exchange you trade, and moving money between them costs time and fees; dust and minimums — exchanges have minimum order and withdrawal sizes that strand small balances; the learning tax — your first dozen trades will include mistakes, and those mistakes must be small enough to survive; and tooling — a decent scanner subscription or VPS for a bot is a real monthly cost that must be earned back.

Taxes deserve a line of their own. In many jurisdictions every arbitrage trade is a taxable event, and hundreds of small trades create a reporting burden that can cost real money in accountant fees. Factor it in before you scale trade count.

A Sensible Starting Point

For most beginners, $1,000-$2,000 dedicated to manual cross-exchange or triangular arbitrage is a reasonable learning stake: large enough that fee math can work on good setups, small enough that early mistakes are tuition rather than tragedy. Prove consistent profitability over 50-100 trades before adding capital — and add it to the strategy that is working, not to new experiments. Capital amplifies whatever your process already is, including its flaws.

When you do scale, scale gradually and deliberately: increase working capital only after a full profitable month, and keep a cash reserve outside the exchanges for rebalancing and unexpected opportunities. Resist the temptation to deploy everything at once — larger size magnifies both edge and mistakes, and the mistakes always show up first. Patient compounding of a proven process beats aggressive sizing of an unproven one, every single time.
