it can be a store of value, much like digital gold.
Here is the problem though: There is simply no logical explanation for its value, be it $300, $3000 or 30K. For any other things there is some kind of way how we price things, for a house we can look at similar houses, for a painting look at similar paintings, for stocks we look at P/E or the business behind the company. Only individual items that are unique like the Mona Lisa can have hugely high prices, those are called collectors' items. But as we discussed, there is nothing unique or unreplacable about bitcoin, and with a fork we can easily double its volume too.
And sure, some stocks stays much higher than its business plan or P/E would allow (looking at Tesla), but not forever. Because forever is long.
So if you want to use beanie babies, cabbage patch kids or pokemon cards as a store of value, so be it. Some people thought they were good investments too. Just don't say I didn't warn you.
