People moving towards gold keeps on growing when they find the market is so volatile. This is to eliminate the loss through the price fluctuation in the crypto ecosystem. This is a random process that happens with time depending on the growth between the both to get a better profiting mutually.
I don't think that is is random at all. Like you said they do it because of Bitcoin's lack of stability.
Right now what matters is that the really low price have been there for a while now and that makes a lot of people diversify their investments, they get more money to invest and since they noticed the market's state they invest it in someone safer for now.
Depends on each individual mindset really, but those who go towards economic analysts tend to draw a pattern based on what they are recommending which is usually the most conservative option.
