Hey.
Is it safe to exchange big amounts on non-custodial exchangers like changelly or shapeshift, or are they designed for small transactions?
I'm a newbie and I want to know if it's safe. Also, I want to know if it's safe to exchange crypto on classical exchanges like binance.
Reading reviews about the particular exchange can help you to decide whether its safe or not.
I dont have experience with the exchanges you mention but If I were you its better to entrust your funds in reputed exchanges to make sure your money is safe.
