When Segwit failed many in the industry saw the writing on the wall, which is that Bitcoin cannot scale in its current form, and there are no plans in place to make it scalable for true global usage. Bitcoin Cash is theoretically a better alternative, but since like bitcoin the mining is so centralized, I don't foresee this being the dominant coin in the far future. I'm still looking for a real option out there. If Ethereum could release user friendly wallets that had actual safety features it would have the chance to dominate, but unfortunately it is not user friendly at all. I would have to say that Dash is currently the best option.
