There aren't 2 "Bitcoin", but 2 cryptocurrency with different name which is Bitcoin and Bitcoin Cash. While i disagree with Bitcoin Cash scaling solution & roadmap, people/services/exchange shouldn't misleading Bitcoin with Bitcoin Cash, especially when users buy Bitcoin but got Bitcoin Cash and vice versa.
Well, most people actually call Bitcoin Core just Bitcoin but there are other people out there calling Bitcoin Cash just Bitcoin, decentralization makes impossible to have consensus amoung every one of us but when I say there are 2 Bitcoins I mean 2 coins with the code written by Satoshi (althought BTC was modified with Segwit). Do you really support the LN?
