I agree, if we look at the Bitcoin business model relative the the mining costs and transaction fees in correlation with what it wants to achieve, we see that it falls short in many areas; cost, sustainability, speed etc. I liken it the the Battle of Hertz vs Avis (BTC, BCH) or even Myspace VS Facebook.. Having market share, brand name recognition etc.. means nothing unless you hold on to it, adapt, upgrade and crush the competition. There is always something or someone around the corner to steal and improve upon your idea...
