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.
I am not surprised that many of what Gavin Anderson had predicted two years ago are now happening with Bitcoin and sadly nothing concrete yet has been done about. As what I read somewhere, the main problem is not really technical but more of a political in nature. It means that those who are vested to decide on matters like this could not find a solid consensus as to what to do with the problem. All of the hard forks we experienced so far are all symptoms of this malice affecting the Bitcoin community. This is one of the disadvantages with a decentralized system -- no single person can decide on the issue hence there is no successful solution so far. Now, I am still optimistic with Bitcoin though as I am hoping that soon these problems can be given adequate and acceptable remedies.
