Like presenting them a trophy that says "You Tried." ;)

It's better than nothing but in truth I think it means one of 2 things:

A) They're broke, and this is actually a very kind guesture for them.

B) They're hardcore HODLers that are trying to set a low standard, since even 1 sat is worth something to them.

I still zap 21 sats at default but if group B succeeds then I'll gladly join them.
