Why I have to hide a letterbox? and what it has to leave to people?

You don't have to :), but if you want to, cf. here:

Basically, a letterbox is a physical cache which contains a stamp (so that the finder can stamp his own field diary with it.)

In the stricter sense – and many letterboxes are done like this – it is often like a multicache, but where you find the next waypoints not with the GPS and co-ordinates, but with a description of how to get there. Often this is "wrapped" in a nice story, and that is what makes some letterboxes really worthwile.

Totally correct. Except that Groundspeak made a change to Letterbox Hybrids recently, in that they must have some "Coordinate component" in them now. So at least part of the letterbox trail now has to have coordinates, a coordinate conversion, projection or such. At least that's what's being enforced by local reviewers in The Netherlands now. Personally I like the alternative ways of getting to the endpoint in older letterbox hybrids better than the now enforced "at least partly coordinates mandatory" guideline.

It's worth noting that letterboxing predates geocaching by nearly 150 years! Details of letterboxing as a hobby can be found on Wikipedia at
