And if you want to be even more precise and correct, there is no such thing as a bitcoin, that's just slang for 100 million satoshis, or bitcoin units.
The total supply is 2,099,999,997,690,000 units.
You mean I don’t have to stack whole coins? 🤯
Yes, there is no such thing, at least in terms of the actual code and protocol, as a whole coin. There are no decimal places in the bitcoin protocol it's just integers.
You can stack as many units as you want. What is colloquially referred to as a "whole bitcoin" is simply 100 million units... which themselves are colloquially referred to as Satoshi.
