They integrated #Bitcoin and dogecoin payment system and and then removed it, according to the information I found it was present since January 2023 but they didn’t remove.
Here’s the info I found:
There were rumors in the community that Tesla added Bitcoin and Dogecoin to its payment page source code. However, upon verification, it was found that Bitcoin and Dogecoin were already present in the source code as early as January 2023. It appears that Tesla did not remove this code when they previously discontinued the option to pay with Bitcoin.
