Recently there was an interview that was conducted with Elon Musk in which he spoke about the investment that he personally has with bitcoin, that SpaceX has with bitcoin and that Tesla also has with bitcoin, stating that all of them own bitcoin and see it as a good way into the future. Naturally so, as they are all his companies. He also went so far as to say that from the European banks, those with negative interest rates for Tesla bank accounts are being redirected to bitcoin investments. This is the first time that I have ever heard of this term. Does anyone in this forum know what is meant by negative interest rates? And is this a good thing from a Bitcoin price perspective? Does this show an increase in investment for Tesla into bitcoin?
