Personal opinion: the elderly will purchase more gold, the younger will lean towards BTC for a safe investment.
I'm not sure the elderly population is going to be buying any more gold right now, especially since the price has gone up so much as of late, nor do I think the younger generation (or people of
any generation) view bitcoin as a safe-haven asset. At least IMO they shouldn't, because how safe is an investment when it's more volatile than precious metals, the stock market, commodities, bonds, and pretty much everything else? Young people might be buying it as an investment, true, but I seriously doubt that's because they want to protect their money against inflation or even hyperinflation.
As far as what OP is asking, I think bitcoin is likely to continue to increase--but there are a lot of variables which could keep that from happening, including what the COVID-19 outbreak does and if we start seeing signs of a recession. Gold I'm not so sure about. Usually when metals start moving upward, there are bad things on the horizon. If we do end up with a global recession (or worse) I'd think gold & silver would continue their trend....and that's not something I'm hoping for.
