A couple of enterprising Tesla owners have been using their electric cars to mine for cryptocurrencies or privacy tokens like Monero. According to them, the most profitable way to mine for crypto with a Tesla is to use a hacked firmware and hook graphics processing units directly to the electric motor. One Tesla Model 3 owner reveals that this way he was able to net up to $800 a month in Ethereum when the cryptocurrency was at its record price.

Profit $800 a month but lose thousands on unseen depreciation on the battery. What a genius.
quick calc:
800usd x 12 = 9600usd per year in crypto, at least 10 years before his battery is completly broke
so the guy is clever, he sold his battery for 96k usd while he can buy a new battery for max 20% of his gains...
more if/when the value of his crypto goes a simple 100% higher in the next 10 years
just my 2 cents
