Bitcoin would have had a great future if the big guys werent so greedy and sacrifised a little of their wealth for the benefit of the whole community. Since they refused to do so (=refusing any attempt to make BTC transfers faster and cheaper) the network is choking itself (=it takes days for a transaction to be confirmed, it costs >$30) and the community is thorn between altcoins.
We will see how this will play out, but my hunch is that we will see a huge market collapse and a "restart" by one of the emerging altcoins that solves the issues that came up with Bitcoin.
Start accepting BCH, Dash, etc, if lightning works out great, go back to BTC, if not, the alternatives are there
(Of course they can look at ETH, XRP, Monero, but accepting bitcoin forks is easier if the BTC infrastructure is already there)
No payment provider is going to take the same risks for BCH again that they took for BTC. No merchant, and also most consumers won't.
