Unless you see gold as bullshit as well. I think it should now be consensus that Bitcoin isn't acting as a transaction tool, but as a store of value, just like gold. There are pros and cons when comparing it to gold as a store of value. But the main thing that keeps up the "value" of Bitcoin is just the belief that "it is a store of value" itself. As long as people continue to believe this, it doesn't need to have traditional value. This is the same as gold. Bitcoin in this sense is even more pure, because gold still has some industrial and consumer uses, while Bitcoin has zero. This belief may or may not persist in the foreseeable future, but it is what it is now. Thinking this is "bullshit" just doesn't really matter.
I'll add that if gold wasn't so impractical to transfer, store and verify we would most likely still be using it as a currency way more frequently (even in our inflatuonist systems, it would likely be seen as a more sound money).
Bitcoin improves a lot on all of these properties while introducing other properties (open/public network, borderless, public ledger, etc.). Its supply/issuance has also been much more stable than Gold ever was (and ever will be if we're to believe the predictions of giant mines and even future asteroid mining).
