Do you think that should bring more users to bitcoin? I mean a way to earn money could bring more users , even If not from fiat users , It will from other crypto currencies.
It will hardly make any noticeable difference
People who are using alternative cryptocurrencies are obviously already involved with Bitcoin in some way. So LN can scarcely attract more people from this substrata of cryptocurrency users. Besides, it is not so much about the times between transaction confirmations on average but about making these confirmations more consistent. I suspect many people would be just happy if their transactions were confirmed within half an hour in most if not all cases. Some people may need faster confirmations, though I don't really think they are making the bulk of Bitcoin users
