Because adding more units is useless, it’s already been tried countless times and never caught on. And bits already has another definition in the technology lexicon.

 Fair. 🤝 

 Whenever I explain it to someone new I just say it's 9 decimal places of a Bitcoin so it's really small and can be used for day to day tx's and they get it, I don't understand what the big deal is, not just you it's everyone yk 

 Forget about decimal places. I tell people 'there are 100 million sats in one bitcoin.' It gives them a goal to count up to and the human brain understands that much quicker and easier than decimal places past about two. 

 That's probably better, I'll try this next time I introduce someone. Thanks!
