A minimum 50000 USD : 1 BTC exchange rate implies that the value of 1 USD = =3D 0.00002 BTC at maximum. However, such a USD value in BTC value maximum makes no sense since the tru= e value of 1 USD =3D 0.00000000 BTC. (on Lightning, 1 USD =3D 0.00000000000 BTC) In particular, the encoding proposed in the BIP does not support a represen= tation of infinity USD per BTC, such that it is impossible to express the t= rue value of USD under this BIP. > * The USD/BTC rate used for the transaction, in standard signed integer s= erialisation, with all leading zeros removed (except as necessary to preser= ve the sign bit).
