How tf does crypto work as a currency?

[Meteor21]

I always hear people buy into it, the value constantly fluctuates. Why can't you just buy into it when the value is high and immediatedly use it before the value plummets? Can someone explain? People talk about buying into it and losing money as a result, but can't you just wait it out until the value increases again? People talk about it as if they're perpetually losing money just by virtue of holding it. I don't understand.

If you buy when the value is high youre probably gonna lose money

Why?

Because assets dont go up and up and up. If a crypto goes up by a lot, a lot of people are gonna sell, so they can get their profit before it drops again, when a lot of people sell the value goes down
