Unfortunately, I think BTC is a bad leader for the cryptocurrency world. Many other cryptocurrencies are capable of change and adaptation. BTC has been hijacked by Libertarians who will guarantee its stagnation. POW is proving to be an inferior, centralized system that waists electricity. Most of the viable projects are at least working towards a POS system that can realize Satoshi's vision.

 BTC is one of the slowest currencies out there, most business is still done with BTC but for those that do business in crypto we would like something as fast as PivX, HLM, and Ripple. fourty minutes for a confirmation is unacceptable. When you're competing with Visa, Mastercard, and American Express, you need to offer comparable efficiency. Plus, mining pools keep forking BTC and BCH in a manufactured drama. It allows them to drive up difficulty and then just switch to another fork.
