Fortunately, my holdings in Alts, at least my two biggest, are STEEM and BTS...two that dont require lightning.
But you are right, I see BTC improving with SegWit and Lightning...it will not be this old grandpa animal people are trying to make it out to be. Also, as you stated, as gold, transaction time is less important. Does an overseas supplier care if it takes an hour to get $125K in payment versus 3 seconds? The banking system takes days.
