When I think more about this, I guess that if people/investors were moving to gold is because they want to have another type of investment, so they choose gold for the next investment. And what I think is how we can spread that money into many types of investment because our purpose is to make more and more money in the future. And by having more than two types of investment, gold and cryptocurrency, we can have the opportunity to make a bigger profit.
you are mostly wrong.
having more than one investment is not going to give you more profit, and also having more than one investment (aka diversification) is not about making more profit, it is instead about reducing the risk of your investment while still making profit.
so when you buy something else like gold it is because you want to have a stake in another market that is not going to drop with bitcoin, or vice versa, you buy bitcoin because you want to have something that doesn't drop with gold. so that if one of them dropped you are not in total loss.
besides OP is not even talking about diversification! he is talking about people giving up bitcoin and buying gold instead. and he is saying they are dong it now that it is not time to sell but the time to buy
