Firstly, when compared to crypto volatility gold looks very stable, but outside the crypto market gold movements of 2-3% are considered big and they do affect whole industries relying on the metal.

Secondly, the price of gold doesn't increase each year---it has gone through a multi year bear market and has just woken up in the last 12 or so months. It's still far away from its all time high of $1.9k per ounce.

Prices can go down a lot in Bitcoin too, so it comes down to what side of the trade you are on..... luckily for people they can make money regardless of the market sentiment and direction thanks to platforms such as BitMEX.
