Thanks for the information. It's still a little confusing, can I make it with any kind of coin?

Depends on what you mean with "any kind of coin". You can look at stakes as a "ratio" of coins you will get.

To be exactly 1 stake conforms the ratio of 1/(Amount of shares circulating). If you get 50% of all distributed stakes, you will get 50% of all coins (which are bound to this offer).

So, yes, you can use stakes for any ICO, altcoin or anything you wan't to offer to people.
