Carsten Otto	5fe147f683	remove check ... The "available" liquidity used in the comparison is not the actual liquidity, but the reduced amount (with a safety margin for fees). Comparing against it defeats the purpose of the safety margin.	2022-05-24 22:39:19 +02:00

Carsten Otto	9593dfd161	allow channels with non-zero base fee ... Note that this is an over-approximation. In the routing cost computation it is assumed that the base fee is paid not just once per payment, but possibly several times. As an example, with a base fee of 2sat and a quantization of 10,000sat (which is the current default), the assumed fee rate is the original fee rate plus 200ppm (2sat * 1,000,000 / 10,000). fixes #31	2022-05-17 10:15:04 +02:00
