Please note that my 546 sats recommendation is not a hard rule. In fact
amounts as low as 330 sats per output might be practical for ordinary users.
546 sats is only quoted because many sites quote it and it appears to be working
fine and the transactions did not have problem getting relayed or anything else.
It all depends on how dust is defined by the Bitcoin client and I have no
intention whatsoever to influence those rules. Please respect the Bitcoin rules.
Another concern about the 546/330 amount is that I am strongly convinced that
every Haircomb user needs to use the same amount for privacy reasons, to blend
into the crowd of other Haircomb users.
This means the migration to 330 sat claiming amount should be flag-day, if done.
