1 BTC should be = 100.000.000 Bitcoin. What i mean by this, is we should start calling the smallest amount of bitcoin BITCOIN. Comparatively we dont call an atomic unit of gold, schwarzeniggel, we call it gold. No matter what quantity it is. However, if we have more gold, we denominate it in Kilos or whatever depending on which area of the world you are in.
Gold is a material, not a unit of measure, just like water or oil or sand. You can't say that you have "2 golds of rice" or that you weigh "150 golds" or even "5 golds of gold". You measure gold, silver, etc in grams or ounces (or pounds or tons for much larger amounts). Likewise, a Bitcoin is a well-establish unit of measure of money. It is equal to 10^8 satoshis, where a satoshi is the smallest "atomic" unit of measure of the Bitcoin measurement system. You can have 5 Bitcoins of money, for example, but you cannot have 5 golds of money.
So are we gonna have wallets displaying how many atomic amounts of bitcoin we have? YES, it is simple without being misleading. One problem arises tho, because even the poorest bitcoin owners will have millions of "atomic" bitcoin atm. So we need to start denominating it, just like we denominate gold..
It will be misleading, IMO. How many Bitcoins do you have? Is that in the "old" or "new" Bitcoin unit of measure?
Imagine that someone tried to redefine the meter to be what is currently a millimeter because small units like centimeter and millimeter are too "confusing" for idiots. Then a new kilometer will be the same as one old meter. How far do you have to drive to work? 5000 kilometers? Wow, that's a long drive! That'll take you days of driving! Oh, you mean "new kilometer", not "old kilometer". That should be a 5-10 minute drive.
The new denominations could probably draw inspiration from the filesystem. The file system automatically cleans up the number when its displaying file sizes. This is the kilobyte, megabyte, gigabyte system its quite easy to understand.
No filesystem I have ever used nor heard about does this (and I'm familiar with the filesystems on quite a few different operating systems spanning decades). Software like file browsers and directory listers (such as the dir or ls commands) display file sizes in kilobytes etc, but the filesystem always store file sizes in bytes or blocks or records.
What you're really suggesting is that everyone uses "new Bitcoin" (defined as the smallest atomic unit currently known as "satoshi") instead of using "old Bitcoin". You're also suggesting that this would somehow be
less confusing to some imaginary users (frankly, I think you're the only user who is confused by this) than simply adopting other names like millibitcoin/bitmill/millie for the smaller Bitcoin denominations.
