Gold is traditionally considered to be the safe haven by many investors and fund managers especially on times of trouble. When there is that pervading sense of gloom, they are looking for something stable, valuable and reliable thus gold easily comes into the picture. However, there is that digital mirror of gold and we call it bitcoin. Bitcoin is likewise valuable albeit it can be volatile but for someone looking for an opportunity for a greater returns this is the best choice. Thus, if things are turning out to be worse in the global economic scene as the result of the ongoing trade war between superpowers China and USA, many can hop into both the real gold and the digital gold.
For stability the choice tends more to gold,The quicker gains certainly do favor bitcoin,it is easier for bitcoin to achieve a 100% gain in just a couple of weeks,it will take gold even years to achieve that same feat
Bitcoin also heavily relies on the market volatility to (re)generate interest from most investors, whether it has the ability to rapidly go up or not doesn't make it a safe investment in a time of trouble. Usually, markets are highly susceptible to major events throughout the world. Because investors are more inclined to invest in more stable and safe assets in times of significant concern, like the poster you replied to mentions, Bitcoin becomes far riskier and even more volatile as the whales begin to exit the market. Gold is a great staple investment for anything less than an end-of-the-economy scenario, and probably better for those situations too anyway, in the eyes of most investors that would participate in the marketplace.
Precious metals have almost always been a safe investment in any case, that won't be changing soon. I'd almost say that a weaker crypto market will be more beneficial to users in the short term, since we'd be able to accumulate more, even if it meant short-term losses to portfolios.
