But I am comparing it if someday will be having the same fate as other known exchanges before that has lost their traction. I am just overthinking but there is the possibility with that long span of time.
We should really consider the possible worst case scenario. Because we don't know the future. At some point, they may encounter big problem that will significantly affect their market value. That's why, in my opinion, bitcoin is still the first choice if you are looking for long term. I can add also eth, as they do have active development team. They keep on innovating their platform. Though they seemed slow but I believe they have strong dedication with their platform.
I think that Binance is doing good and they're leveling up as much as they can which the first exchanges doesn't have. They keep on adopting and making updates that shouldn't be missed by them for their users.
