Bitcoin LN will destroy the BTC network, what will happen next?
same as what happened to golds old 1900 medium of exchange, replaced by bank notes.. and now bank notes being swapped for brass, nickel and copper coins.
what needs to happen is BITCOIN needs to scale to keep people using the bitcoin network and maintain it regularly/daily. not be shunned away to another network being told to prune their wallet software and not maintain the blockchain, and not use bitcoin network regularly.
and they will want to resort to a previous BTC backup (to the closest blockchain of the last fork). It's not like that?
