I have to wonder to myself why Bitcoin would rebound if there are better technical solutions that could become more inclusive of a wider variety of people?

BTC and BCH ( as well as other coins of their ilk) have the built in anti-inflationary aspect of having a limited supply (as opposed to steem) which plays on supply and demand. As money comes into the crypto space and market cap increases so does the price of Bitcoins. It seems that simple.
