Search «make money online» and you'll drown in promises. This guide is the opposite: a sober look at one specific, mechanical way people earn with crypto — arbitrage — what it actually pays, what it costs, and where beginners lose money.

Why arbitrage attracts beginners (for the right reasons)

Unlike trading on predictions, arbitrage doesn't require guessing where the market goes. You profit from a fact that already exists: the same asset priced differently in two places. That makes results less about luck and more about discipline, speed and fees — skills you can build.

The realistic math

With spreads of 0.5%–3% per loop and several loops a day, monthly returns depend mostly on your working capital and how many quality opportunities you catch. A trader with $1,000 working capital catching one 1% loop a day is looking at roughly $200–300 a month before fees — not a Lamborghini, but a real, repeatable income stream that scales with capital and experience. Volatile days pay several times more.

Where beginners actually lose money

  • Closed networks: buying a coin, then discovering withdrawals are suspended — the spread dies while you wait.
  • Phantom spreads: a price gap with no real volume behind it.
  • Fee blindness: a 0.8% spread minus 0.2% trading fees ×2 and a network fee can be a loss.
  • «Guaranteed profit» schemes: anyone promising fixed daily returns is running a scam. Arbitrage income is real but variable.

The professional workflow

Professionals don't hunt manually. They run a real-time scanner that does the mechanical part: DexAgent compares prices on identical pairs across 10+ exchanges (spot, futures, and DEX like Jupiter on Solana) every few seconds, filters out pairs with blocked deposits/withdrawals and shows only actionable spreads with volumes and network status. The human does what humans do best — judgement: which loop to run, with how much, and when to stop.

Starting checklist

  1. Accounts on 2–3 major exchanges, verified in advance.
  2. Working capital you can afford to lock temporarily (start small — $200–500 is enough to learn).
  3. A scanner subscription — from $30/week, cheaper than one missed opportunity.
  4. A spreadsheet. Track every loop: spread, fees, time, result. After 50 loops you'll know your real numbers.

Crypto assets are volatile; past spreads don't guarantee future ones. This is educational content, not financial advice.
