The benefit is only one there and that is the interest. We don't usually count the price but for good coins, it's already expected that they will do better in the long run. Apart from the benefit there must also be a disadvantage and the one that I can see here is we are storing our crypto on a centralized entity.

This was risky because they have a full control our money. I think there is a way to stake coins without needing to deposit your crypto into somewhere else. We better do this instead. OP is choosing between gold and crypto but why not he choose both? He may only need to put more in crypto because we are used to them and we know that they have better potential than gold.
