Wallets generally have to unify balance between chain and lightning which is a complication. If you show the balance with a bolt, a user may assume their entire balance is on LN, when there could be a chain balance reflected in that

Amount is a factor too, it should really switch when the decimal value is greater than .009 or so where a chain payment is more viable

I was sympathetic to bits because I think people get hung up on <100 sats left in Lightning wallets because of fee reserves needed, and in chain context the last two digits are superfluous since tx fees will eat them anyway, they could be a smaller font (like cents)

Bits for Lightning and Chain balances bridge the gap a bit with long decimal values, problem is its not really a thing beyond an aesthetic abstraction and died before this was realized

Sats aren't mentioned here but you know immediately by looking at it what the unit is

Biggest drawback to bits in UX may be that if this was was a .11 instead of 11 you might think it was cents had I not put the fiat value underneath it
