I added this to the OP.  Fun to see the price of Cybertruck fall so much in BTC terms so quickly.  Could you imagine what this forum's reaction would be if Elon posted here?
 "Tesla is a scam!  Elon Musk isn't being honest about the value decline of his vehicles!"  LOL

More seriously, this is a very good example of why things cannot be priced over time in BTC terms.  The price change is 100% a reflection of Bitcoin's exchange rate movement and nothing to do with the underlying asset, in this case the Tesla Cybertruck which has only become more valuable over this price period.
