The Lightning Network could help Bitcoin become faster and cheaper to use
to my mind, LN is an unnecessary thing. It's pointless to create a payment channel for the sole purpose of sending an off-chain transaction, since it requires a transaction on-chain to open the channel (and another one to close). You might as well just send an on-chain transaction instead; you do not need the LN.
Ofc, you r right, you can always use on-chain transaction. Don't you think LN's idea is really inspiring one?
