Bitcoin is a volatile asset, but in short term. If you want to hold bitcoin for a long time and not selling, it is a store of value. Bitcoin price has proven that up to now.
Bitcoin is superior to gold because its total supply is limited and not more than 21 million in total. But gold is still superior because it is the asset with the largest marketcap in the world.
Bitcoin is superior and much better to gold, but it is way more risky that I don't find it a safe haven asset. In fact, I find gold as a safe haven asset than bitcoin.
