Afaik the lightning network currently supports the 15th decimal place...
Cute, but unless
BTC is worth $10 million what does that realistically achieve? Where are you going to spend $0.0000000002?
Does that have a practical use case besides being a proof of concept?
yeah it could allow for more transactions per day which would help btc scale as a currency.
Is it my preferred solution no.
I prefer
btc to be like a 10000 USD treasury bill
LTC for 500-10000 USD transactions
Doge for smaller USD transactions
I am willing to do some LN support as a hedge against my preferred monetization of BTC+LTC+DOGE
I am in the position to do it so why not.
