Hedgefunds and billionairs are already starting to buy in. Banks are fighting it because they feel treated by it (proves its succes), but many of them are buying in too (may be to manipulate the market or to have a big stake if they can't stop it). Countries like Russia and North Korea are interesting in it because it undermines the USD and also Estonia, Japan and Australia are extremely friendly. I suspect these countries will start buying bitcoin for their treasury soon if they aren't doing already. Remember that when some countries start, an armsrace could start because the first to buy in buys cheap and the last one pays a high price.

On LN i disagree, it will be a very good way to scale the smaller payments, there is totally no need to do this on blockchain. It will for sure displace Dash and other alts, exactly the reason why so many alt investors are against segwit.

I have many sources of information and for sure reddit isn't my main source. Good luck staying heavily invested in alts and rejecting bitcoin, but please not try to bring this FUD to people who ARE interested in Bitcoin.
