Electrum has this since a while but slightly different:

Looks like this then;

But I think how Peach formats it is better for BTC<>sat conversion, yes.

So 0.09 090 372 instead of 0.090 903 72

Big fan of the solution too. This has been cycled here in past, there are couple options for what to use for the separator, e.g. 1.23'456'789 BTC, but spaces work, especially if you can gray out zeros in front.

Not a bad UX idea at all. I dig it.

Satoshi came up with this originally. Bitcoin has 8 decimal places, like the dollar has 2.

Seedsigner came up with this idea originally . And I like it too

Thats pretty cool

Now I feel smart since I've been doing this mentally since forever

Nice UX. I really like how the leading zeroes are greyed out as well. Very visually intuitive. That said, I believe further into the future, especially as the purchasing power of bitcoin continue to increase, sats will be the unit of account and we will be fully on a sats standard, without the need of BTC denomination.

Looks amazing. Obviously we can't have the best of both worlds but I do think denominations in both BTC and sats are incredibly helpful if you use bitcoin a lot for bigger transactions (which I sometimes do reasonably big ones).

I figured showing both would help me solve this when I implemented it, but I might steal these idea from peach wallet too: https://btc2fiat.me/?q=0.15+btc

this is nice UX imo

i think this is better than other btc-sats visualizations, but i wonder if we need to denominate in bitcoin at all.

maybe this is an important feature for wallets, but i think most lightning apps will be just fine without any btc denominations at all

The Bitcoin Design Guide also has tips on formatting units, including parts of what Peach does.

I think it can be a bit simpler. I would remove "sats" and replace the bitcoin logo with the bitcoin unicode symbol. Why not just use "₿ 0.00 000 000"? with the subtle color treatment of highlighting the non-zero amount? That way you don't have two units competing for interpretation (bitcoin logo on the left, sats on the right - which one is it now?). It will still be read the same way.

Overall, I think this solution works well for the bitcoin-savvy Peach audience in the big total balance display. For use in other parts of the UI, where there is less space and the numbers have to be shown smaller, this way of formatting gets pretty cluttered, particularly if you carry over the colors. Simplifying to just sats or bitcoin is often a better solution there.

And more as a side note, because this is often ignored, every country has its own standard for formatting units (examples). If you force your preferred formatting on the whole world, it will not be intuitive to them. Best to use a library that automatically handles unit formatting (browsers even have this built-in).

I think to many zeros and people won't adopt or will get ripped off.

I like kilosats for the next few years until sats are worth more.
