History- it's never going to catch up. Gold has been used for trading for thousands of years. Even if we compare that gold had an ETH long time ago BTC is nowhere near catching up.
Gold is always going to look better historically.

Price stability - it's mostly about the size of the market. Bitcoin is still tiny. We'll start comparing in 10 years because I believe it will catch up in capitulation and become much more stable.

Bitcoin is already as accessible as gold if not more. You can buy it anywhere in the world even in ATMs.
