I'm curious about what would be the best approach if I were to start my own business and try to accept Bitcoin as alternative payments other than cash.
I know the Lightning Network is the way to go for fast transactions, but what if a customer can't use it due to liquidity issues or any other reasons and has to resort to on-chain transactions?
would I make the customer wait for the standard 6 confirmations? or 1-2 confirmations would be secure enough?
