Tesla and Bitcoin are very different entities.
Tesla is an over valued but profitable company with a good future ahead of it e.g. market leading product, ahead of the competition in technology and a devoted fan base who happily buy their products.
Bitcoin is a speculative asset with no underlying value and no real purpose (it’s not a fiat currency and never will be).
At some point Tesla will get corrected, or eventually it’s sales might grow to the point where it’s current valuation isn’t too insane.
Bitcoin is totally unpredictable and will suffer massive peaks and troughs as speculators come and go.
Bitcoin has crashed before without any real knock on effect to the rest of the market. I suspect Tesla will only get corrected during the next tech rout, which is probably a while away yet.
