I will exchange my cryptocurrency with the TESLA car if I feel my return is satisfied. There's nothing wrong with taking profits in crypto investing and sometimes buying something I love gives me energy, inspiration for my next investment.
Enjoy the fruits of your labor boldly. Sometimes that's a good thing. I have seen many times my profits are lost so I support cash out and shopping.
This is what we called rewarding yourself from a hardwork you have done and if that is including rewarding yourself of Tesla car using your bitcoin token or ETh then nothing wrong with it.
Nothing wrong with enjorying the fruit of your labor and to be honest working with crypto isn't easy as it seems and also the fact of earning a profit in crypto was not also easy as it seems, there is no easy money in crypto.
Just always keep in mind that you just have it in your extra peofit and not taking all your profit to buy this.
