19k 20k etc are intimidating prices but thats a result of bitcoins supply being fixed at 21 million. its way too scarce for the adoption thats happening now. Satoshi Nakamoto thought of this and he added 8 decimal places to BTC. This means the smallest unit of BTC is 0.00000001
Why am i bringing this up? Because we dont have to use BTC as the base unit. We can use for example bits/ubtc instead which i show in this chart. For one thing its more comforting trading a base unit that trades at $0.02 as opposed to $20,000. But also it makes pricing things a bit more easy.
bits/ubtc is what the denomination i used is called. have a nice day
