If the winner is rich and lives in a country where Metawin keeps the Tesla Cybertruck, then taking a Cybertruck as a reward is a good idea but for the rest of us, Tokenized Tesla is really a good option.
It depends on the winner's stance and favorite like does he like Tesla and Electric cars.
No way to predict what the winner will do bases on their nationality, living location or socioeconomic status but they will have two options to do, that is good.
There are still some countries where people aren't legally forced to pay tax on such rewards if that's something digital. I mean, it's perfectly possible and safe to not pay taxes on such rewards in some countries (for citizens).
It depends on existing laws and if you claim the tokenized Tesla Cybertruck but later want to cash out, if existing laws in the country requests you to pay tax, you can not avoid it legally.
I am not here to judge Tesla because a giant company like them do have many enemies but Tesla Cybertruck products will need to be used by more customers and their quality must be verified by customers and time.
