Choosing gold and silver is a behavior of investors who cannot break away from traditional investment preferences and do not want to take too much risk. Investors who diversify their investments also prefer gold and silver along with their Bitcoins. Traditional investment preferences prevent many people from turning to new investment instruments because it is generally difficult for people to give up their accustomed behaviors.
The volatility in the price of Bitcoin creates opportunities for many investors. Most of those who prefer Bitcoin over gold and silver make money at certain periods thanks to this volatility. Since Bitcoin is an investment instrument that has proven itself in the long term, it has become one of the investment instruments preferred by many people, like gold and silver.
Bitcoin is just like any other asset. You invest in it, with the hopes of turning a profit in the long run. Whenever you become a success or a failure, greatly depends on the strategy you follow. If you take advantage of the ups and downs (volatility), there shouldn't be a problem. Remember, Bitcoin is not a means of achieving financial prosperity. It's not a miracle worker. You could lose it all if you're careless.
A sound strategy would be to invest a portion into Bitcoin, Gold, and Silver to minimize risks of loss as much as possible. But that's just my opinion. Do your own research to help determine what's best for you. Can Bitcoin save you? That totally depends on you. Now, fixing the world with it, that's an entirely different story. It will never happen because governments won't allow it. At least, we have an escape route from the corrupt Fiat money system. And that's what truly matters.
