Lightning network?
Ohh that's crazy!
Why altcoins are growing more and more? Its because most or maybe some of those altcoins, correctly me if I'm wrong, want to solve what bitcoin couldn't solve. Maybe, I guess we have to consider and take some time studying those altcoins, not really all of course, there are plenty of them lol. We sometimes forgot to get out of the box. We focus much attention to bitcoin and maybe on ethereum or ripple. Those top 3 coins in my opinion are already in prison guarded by banks and financial institutions. Maybe try looking those privacy coins, anonymously private ones. Those coins that are really solving REAL problems for the common good.
