For me this depends a lot on what kind of assets you already hold. There isn't one easy answer that tells us to only hold bitcoin or gold. For example, many people have gold in form of jewelry, cutlery or other form of arts. Even if the gold price is around his ATH it might not be a good idea to sell those things. It's not only the commodity price, but also the sentimental value we need to consider. Holding onto a gold necklace from our grand parents is fine, even if we would make more money switching it's value into bitcoin. For me the best is to have a mix of the three with a stronger focus on bitcoins for the future.
