Why use market cap in your argument if you don't care about the stocks??
The issue with Tesla is that it is taking payments/deposits for vehicles that it cannot deliver.
I have no issues with the product or concept. My issues are with the company and its management.
I use the market cap as an argument because they got more than other good known companies. And if it is just a Ponzi how can this be possible. For me is moor market cap = more trust and more success.
It's just 1'000$ wich you can take back when ever you want, so every ones own choice. The car will be delivered but with a delay.
This is individual, every one has his own opinion on this :)
