Sadly, there are still people that keeping their funds on exchanges so that they're ready to sell them asap. But most of them are just keeping it there for storage purposes and they can't determine whether they'll sell or not when the bull arrives.
While some may think that they're wise enough to keep it there because of the current high fees again, it doesn't makes sense if you have no intention of selling.
Ain't that the truth? I guess some people just got a really low price goal so they keep it in exchanges in case they need to get their profit or that they've finally reached their goal. Totally agree with the part of no intention of selling then don't store it there but still it's still a risky thin for someone to do that, learning how to store your own bitcoin is the only way and that's the freedom that we all should be striving for so it's a mystery to me that people still do this kind of thing, to each of their own I guess.
