Thanks to Lightning Network, the Bitcoin network can overtake VISA in the speed and number of transactions

According to Christian Decker (Core Tech Engineer at Blockstream), each Lightning Network channel can handle 500 transactions per second.

If such channels are more than a thousand, the Bitcoin network throughput capacity will overtake such large payment systems as VISA. Lightning Network provides much more privacy because transactions are combined into groups and it is not possible for investigators to identify, from and to whom the transaction has been sent. At present, 1700 LN-nodes operate on the bitcoin network.
