Not sure there's any response possible for that one. "I don't know how it works, but I think it's dumb."
> Now the transaction fees are exorbitant.
Every standard sized bitcoin transaction bar the past three days (and those will too), that people paid over 5c for has been committed to the blockchain.
Replace by fee is a thing, as long as the tx is unconfirmed it could be replaced. You're effectively saying the wait time is now 3 days unless you want to pay a fee of several dollars. So that rules out most transactions.
How do you pay for anything given those restrictions?
Then you don't understand how bitcoin works, so it's probably best you refrain from commenting on bitcoin architecture.
Lightning network hasn't been rolled out yet. It has nothing to do with our conversation.
