Thanks for sharing this news with us, and it's an boosting sign in the perspective of growth of Bitcoin and it also help in the loosen up of the speculations which are surrounding Bitcoin from long time. In my opinion an lightening transaction network will provide an efficiency. But in contrary in my opinion the Dominance of Bitcoin on the Cryptocurrency market should decrease because if price of Bitcoin decreases then inturn it leads towards the pulling back of the prices of Altcoins. Wishing you an great day. Stay blessed. 🙂
