Bitcoins easily. Who invests in gold these days? Only people 50+ in my experience.

When my generation, the tech savvy Millennials, wants to invest in safe haven assets some time in the future, I think they will go for an asset that is more limited in supply, more transportable, divisible and fungible, easier to secure and easier to trade than gold, namely BTC. Not to say that bitcoin has greater potential for price appreciation than gold, which seems to go nowhere in terms of value.
