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.
Except many will be only running up the price on exchange, so isolated from the issue. And if there is a sudden realisation of the problems, there wont be an orderly transition to alts, it will be a flight for exit. So the problem needs to be addressed in a rational way, however we've seen how well the community copes with that, with the block size changes.
