Lightning Network can become the answer of bitcoin to the low commission of altcoins. The exact timing of launching LN in the main bitcoin network is unknown, and before that beta releases of applications are required, however, as the developers are convinced, the full-scale activation of the protocol can become one of the most important events in the history of "digital gold".
This became especially important against the backdrop high commissions of the bitcoin network: in addition to instant payments without waiting for confirmation and potentially higher level of user privacy, one of the main advantages of LN is the decrease in transaction costs.
