# Small capacity channels are problematic for many reasons. As the onchain fees start to become
# significant compared to the capacity, things start to break down. e.g. the counterparty
# force-closing the channel costs much of the funds in the channel.
# Closing a channel uses ~200 vbytes onchain, feerates could spike to 100 sat/vbyte or even higher;
# that in itself is already 20_000 sats. This mining fee is reserved and cannot be used for payments.
# The value below is chosen arbitrarily to be one order of magnitude higher than that.
