It is always best to take precautions and be safe when trading on Gemini or any other cryptocurrency exchange. Taking everything off Gemini is a wise decision, as it can help protect your funds from unexpected liquidity crises, as seen with FTX. To ensure your funds are safe, you should also consider diversifying your investments and spreading them across multiple exchanges. Additionally, it is important to research the exchanges you are investing in and to only invest what you can afford to lose. By taking these measures, you can help protect yourself from unexpected losses and maximize your chances of success.
