Spending Bitcoin
is aldeady being used as titleBitcoin Clients rather than onchain mainnet
Again, term "Bitcoin Client" could also mean the software that is being used to access users fund (i get that you're referring to how many Onchain implementation out there)
You also need to look at the whole picture, i can't just change
ONCHAIN MAINNET
to BITCOIN CLIENT
because it will break everything abovereply
ONCHAIN MAINNET
section ?
