what @elonmusk is doing with teslanya is something very clever, it is better for him to accommodate bitcoins through Tesla sales than he himself has to buy bitcoins, because it reduces the costs that have to be incurred for all transaction fees when buying bitcoin.

on the other hand, of course, for those who want to buy Tesla, it will obviously make it easier because there is no need to exchange it first for fiat, which obviously costs nothing. both parties benefit equally in this case and of course this will reduce the authorization to be simpler, only one cost and not two times, of course it is very profitable.
