Private channels should have their own dedicated 'min-funding-satoshis' setting

See original GitHub issue

Issue Description

IMHO there is no reason, why peers shouldn’t be able to open small private channels. Minimum size should be configurable with a dedicated min-funding-satoshis setting for private channels.

Edit: The idea is not to enable super small private channels, but rather to be able to raise the limit for public channels without affecting private ones.

I can imagine setting some reasonable values like min public=5m SAT, min private=1m SAT to not make it prohibitively high for mobile wallet end users who wish to open a private channel to an arbitrary node. Dangers of way too low limits can be put in a config comments, there are quite a few of such warning there already.

this! My min channel size is 5m but I don’t mind offering 1m or 500k min size for private channels (depending on BTC price) to help out mobile users.

There is no added risk here as long as you set the same standard values for both and inform users that they should be aware what they are doing if they go lower.

I think I might have used poor wording in the parent post [fixed now]. Realistically it’s more about going higher than standard setting with public channels, not lower with private.

Yes, just speaking from my perspective: I did encounter mobile users frustrated with capacity requirements.
