That's actually NOT right. Gold has also been going up, but a much slower speed, with much lesser volatility if we compare it to Bitcoin. It's currently in its own all time time high right now. For people who don't want the volatility, and merely want a slower surge in price, then Gold might be the more preferable investment.

¯\_(ツ)_/¯

But Gold has taken it more than 20 years for its 10x. Bitcoin can surge to 10x in mere months.
