It will be interesting to watch BTC development move forward.  There was a huge portion of the community pushing for bigger blocks who have now shifted there holdings towards BCH.  These people will now support keeping BTC crippled at 1 MB, as they believe that shifting value from BTC -> BCH is now the best solution.  So we have a situation where both small-blockers will be pushing for no block size limit increase AND big-bockers (like me) will also be pushing for no block size limit increase.  So I think it will be difficult for BTC to scale if Lightning Network (LN) doesn't work out as planned.
