I am trying to map some Insane Diffs for my Maps, before that I avoid to make it because I was never sure how or when they would fit good.
I got an example here. I do not search for Mods, so please read this carefully.

I asked some of my friends and they meant that many jumps are random, and that the Map has no real building..
I don't know how I should make Jumps (except of the point, that they should fit with the Music), but if I already do that..
So, how people make them? by increasing the Distance Spacing? Or just by feeling?..

Well obviously you increase distance spacing for a jump but it's to you to make the decision whether you want to map something a certain way.

Usually I make jumps on notes of emphasis. For example, (I will be using your map for all these examples) at 00:05:614 (6,1) - a new melody comes in (combo 1) and that first note is the main beat and is "emphasized" more. You can just feel that that note is very important. So, right there could potentially be a jump. However, at 00:06:342 (4,5,6,7,8) - where you increase spacing, your jumps don't match the up with the music as well. Some people may not even put jumps here because the melody is just repeat itself and nothing that interesting is happening. Other people may put jumps at 00:06:160 (3,4) - on combo 4 because the melody reaches a high point and it stays for a quarter beat. I can't really explain much more about why it's "emphasized," but you can just feel it. When you feel this sort of high point in the music, it is also a good indication for a jump (so for example, like http://puu.sh/11EXF I also increased the spacing of combo 1 2 and 3 cuz it makes more sense, because the music just got more interesting with the addition of a new melody and it's getting more exciting, hence I increased the spacing to 1.0x to match that)

Also for 00:07:796 (8) - you could do something like http://puu.sh/11EZW to follow the music more and have a jump there like that.

And at 00:15:978 (1,2,3,4,5,6,7,8,9,10) - you can definitely hear a change in the music. Something interesting happened. Now, because of that, you can (or maybe not, depending on what you think) increase the spacing/make jumps http://puu.sh/11F1X

just some things to think about. Just because I said you can doesn't mean you should lol. you just get a feel for it after a while, and you begin to develop your own ideas on how to map.

Or you can make it a super jumpy map and put jumps every where like a bawss

Use jumps only when there's a lot of emphasis in the music. As in, a lot. Not a slightly accented note in the middle of a phrase.

If you have to ask how to use jumps well, then use them sparingly. Too many people force them and they defy the music in a way which doesn't follow it well at all.

Anything shorter than 1/1 is usually a bad use of jumps, because any accents can be inflected with angled patterns with regular spacing. If there's really a lot of emphasis with 1/2 notes, then a few small jumps of around 1.2x spacing can be good. With 1/1, I feel like it's much easier to get away with jumps, as they are very easy to hit for anybody with a reasonable amount of experience.
