https://www.technologyreview.com/s/540921/the-looming-problem-that-could-kill-bitcoin/This was over 2 years ago. Those that ran the price up over the last $9000 probably have no idea about these issues. With things the way they are they will find out...and that's when the panic selling will begin. This is not FUD...it's FACT. Everyone was warned by the top dev...and nothing was done. Now is a good time for everyone to look into futures and options to hedge their bets if they cannot sell.
It is now evident that fees and scalability issue aren't the obstacle in the way of bitcoin and its price. If so is the case then people would have already migrated to any of the rest of 1000+ cryptocurrencies or there would have been flippening already with some forked coin. But this isn't the case. People aren't affected from transaction delay or high fees while purchasing bitcoins. The central idea behind bitcoin has been changed and people are more interested in buying, holding and selling at higher prices rather than using bitcoins in general transactions.
It only started to really get bad in the last couple of weeks...as in deal-breaker bad that will cause people to scratch their heads and ask themselves, "What did I get myself into?" It's like saying that it's ok that your dog poops and pees all over your house because he's an expensive dog and no one will mind. You might be able to live in piss and shit, but your wife or significant other will get fed up and force you to sell the dog...or they'll move out.
People do not want to invest in broken technology. They will look for an alternative without the current flaws. I cannot imagine people want to hold onto something that is becoming more useless with each new price high.
