I sincerely think what all this people should have been more concerned about now would have been how to solve the low block confirmation speed and the high transaction fees issues. Vendors are loosing it. Alot of vendors are dumping bitcoin for Ethereum.
Take a dive into lightning network, and see for yourself how this tackles the confirmation times and higher fees. It also allows Bitcoin to process millions and millions of transactions per second.
That's a staggering number for sure, and especially because of how Bitcoin for years has been able to process only 7 transactions per second. It doesn't require anyone to be a rocket scientist to understand its potential.
Once lightning network is in place, it's not Bitcoins that are being dumped for altcoins, but vice versa. Nothing comes even close to Bitcoin in all aspects, and everyone knows that.
