@archliberal So it is has been a few years since I was an "expert" in this as much as anyone can be an expert in this but it basically any amount of bitcoin is like a trophy where each holder signs it. When it divides it gets really messy because each discrete bit Satoshi can have a list of prior owners. When you want to make a transaction you basically gather all your trophys together to show to the chain and then send to someone else.
