Musk says that bitcoin received as payment will not be converted to fiat, however, there are obviously limits to this. Tesla currently pays its suppliers and employees in USD, and if they are receiving BTC for their cars, and not converting the BTC to USD, they are effectively buying BTC. At one point, they will have accumulated too much BTC and will need to dispose of it somehow.
The real big news will be when Tesla is able to start paying their suppliers and/or employees in bitcoin.
Agree. But at least they are consistent in using bitcoin as a "reserve currency".
If you are using your unit as a Store of Value, it makes sense to convert your unit into the MoE as later as possible.
So for sure, they will pay their suppliers and employees in fiat, for the time being, but they will hold their reserves in bitcoin.
This makes sense, until, as you say, everyone will be directly paid in Bitcoin, then converting into fiat will be totally useless (I guess the last legit use of fiat money will be for paying your due taxes).
