The way I see it, there are two possible reasons for this:

One, it's possible that weak hands have already been shaken out. There haven't been any crazy slides that can be attributed to one or two things happening worldwide, so it's certainly possible that there are far less panic sellers at the market nowadays.

Two, it's possible that people have already been desensitized to exchanges being hacked. Nearly everyone who has spent some time in crypto would know not to keep their money in exchanges anymore because it is already assumed that poor security is a given.

But yeah I guess we can only really speculate. It seems to be working both ways because no piece of good news can power a surge either.
