Hard NAK.

A minimum 50000 USD : 1 BTC exchange rate implies that the value of 1 USD = 0.00002 BTC at maximum.

However, such a USD value in BTC value maximum makes no sense since the true value of 1 USD = 0.00000000 BTC.
(on Lightning, 1 USD = 0.00000000000 BTC)

In particular, the encoding proposed in the BIP does not support a representation of infinity USD per BTC, such that it is impossible to express the true value of USD under this BIP.

> * The USD/BTC rate used for the transaction, in standard signed integer serialisation, with all leading zeros removed (except as necessary to preserve the sign bit).
