Exactly, if we compare the growth rate then Bitcoin is always ahead of Gold which doesn't mean people investing on Gold decreased than crypto investors. It can be comparison that can be shown for a layman to make them realise they can also add BTC as their asset in their portfolio.
Myself investing on both Gold and Bitcoin since I am started making money, even though Bitcoin is highly profitable still I can't avoid Gold cause it gives the security than nothing else.
We all know that investment requires both safety and profit. Gold is for safety, BTC is for profit - it is the right choice for professional investments, and I believe that you are such a professional investor. For young people, they may prefer BTC to Gold. MicroStrategy also only accumulates BTC and not Gold, perhaps because it is a software company and believes in the Internet future.
For most people or investment funds, I think a small portion, less than 5%, allocated to BTC will generate significant returns while still keeping risk under good control. Crypto is still a new and unsustainable field, but only by accepting this risk can real, superior returns be generated.
