There shouldn't be any 'or', always best to diversify your portfolio. Keeping some in gold is a safe bet compared to crypto where the bigger gains (should) be made. My advice is keep at least 25% in gold (or any other 'real' asset like property etc.), and if and when your crypto portfolio makes gains, keep taking the cream off the top and putting it into your 'real' assets to maintain that balance. Obviously all your choice, but that would be my plan.
