For most of us who are holding coins outside of centralized exchanges, is it sound to transfer the coins to exchanges now or in spring 2025?
Decision to be made on this should be a product of your investment plan and timeframe. Do you plan on selling anytime from now?

But if you planned on extending your hodling to next four to eight years then it would be risky leaving your coins in a CEX for that long.
