That is not raising cash, that is still borrowing, when the asset value falls below the leverage level, no more borrowing and a margin call begins ...... Musk has already been at that point when Tesla was a dirty word, SpaceX is headed that way because both Tesla and SpaceX loans are approaching their roll over dates, no improvement in perceived asset value will mean the whole show is already over leveraged .... and the house of cards comes tumbling down ..... Financial institutions don't lend money on dreams and SiFi fairytales .... although they did in the last financial crash, so who knows ..... The think that many still haven't learnt from the previous crashes, there is no such thing as "Too big to fail" T1 Terry
