I think Tesla is extremely overvalued, very curious to see how it plays out
It is quite childish to insist that someone who questions the value of Tesla must put their money on it. It’s akin to lame-ass playground bullying: “You don’t like that, so I dare you to eat it!”
Setting up an account with a broker to do options trading requires a lot more capital or margin and requires a lot of research to understand puts/calls, hedges, etc. Buying stocks of other companies you believe will grow is a perfectly fine approach.
One can have an opinion about a company and not do anything with the stock. One can also have opinions about laws, political candidates and ice cream flavors and not do anything about them as well (at least in the US, other countries may silence political opinions).
