You are not wrong to be skeptical.
I have made a little money trading a Bitcoin ETF lately. It’s definitely an asset to be played with gambling money only, but someone I know turned a small ‘bet’ into a big return. I just cautioned him to cash in some of his winnings from time to time.
That kind of digging is what saved me from the dotcom bubble (and I was a very early investor in Amazon and a few other relatively solid dotcoms and could have gotten trapped if I hadn't luckily been very honest with myself about what I saw in the weeds).
Tesla is a little bit like that. It has some incredible technology and produces a great product (the cars), but it is heavily dependent on artificial demand (created by the media/culture and made affordable by the government).
As you probably know, when you get way down in the weeds on any subject, you start to wonder if you haven't missed something. Ergo, I might be missing the intrinsic value of cryptocurrency just because there is a massive amount of detail down in those weeds.;-)
