// FAQ
Is crypto arbitrage still profitable?
For professionals with capital and speed. For retail, the gaps visible on free screeners are usually smaller than withdrawal fees and slippage. Treat arbitrage features as a nice-to-have, not a strategy.
Which platforms offer arbitrage bots?
Bitsgap (spread arbitrage across connected exchanges), Cryptohopper (exchange and triangular arbitrage in the Hero plan), plus specialized screeners. All are subscription-gated.
