As the price of bitcoin increases maybe it would be easier to speak in mBTC for little purchases.
Now one mBTC = 2.59 USD. For example a day one steam game is worth 60$ so it's 23.20 mBTC. I think it's much clearer than 0.02320 BTC.
So we have a bitcoin, a mBTC (0.001 BTC), a bit (0.000001 BTC) and a satoshi (0.00000001 BTC). Bits and satoshis are nice, they're short and easy to pronounce. Plus satoshis can be shortened by sat/sats.
As a community maybe we should find a brand new name for mBTC and easy to use on a daily basis. If you have ideas, I will make a poll with all of them in another topic !
