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.
Fact. Those piling into Bitcoin over the past few months know little about these issues because most generally never have and never will use Bitcoin (or even own them!). They are investors who intend to hold, probably on exchanges or site wallets, and with their eyes on thousands of dollars of profit, the small matter of fees won't be a concern.
Fact. I still haven't found a method with lower fee costs to transfer the values I do as a regular user.
Fact. They can hedge all they want with futures but the ones available now can't be settled with Bitcoin.
Arguable. Scalability is a good problem to face. Many alts would love to have this problem.
