Fast payment: Pay almost instantly.
Not dependent on the miner: Transactions do not need to be approved and verified by the miner to run.
Receiving micro payments: Previously, micro payments were very uncomfortable to do on the Bitcoin blockchain. Now this payment is very possible thanks to Lightning Network.
Receive multi-signatures: Transactions will run if everyone present in the channel approves.
Reducing load blockchain: With many transactions running in the chain, this network reduces the load that must be taken by the main chain.
Reducing waiting time: Because the transaction runs outside the chain and without the intervention of miners, there is a small chance of waiting time. This helps scalability because it will increase the number of transactions that occur every second.
