BTC at silver market cap

It is often said that BTC would reach $100K per coin in the next bull run. Whether this would materialize or not is not the point of this post.

At $100K the market cap of BTC would be around 50% higher than the current market cap of silver. Silver has been regarded (rightly or wrongly) as a store of value and indeed its price fluctuations are nowhere near those observed in crypto space.

If BTC reaches a market cap that is 50% higher than that of one of the existing forms of stores of value why would anyone expect BTC to continue to exhibit the wild swings it has exhibited so far? I would expect the price to fluctuate within bounds similar to those of silver and the price to not fall much below $100K once it reaches there.

Any thoughts?

Edit: silver is a random example; I could have used gold instead and had the same argument.
