How to giveaway coin to Bitcoin owners?

[wsxdrfv]

I know Bitcoin Diamond give away some portion of their coins to Bitcoin owners for just free and without any acting of owners. One day it just generated even before knowing of that.

Their intent of this act is of course for promoting & advertising their coins?

Then how they perform this? Are there any code example of executing this?

Thanks.

A Forkcoin isn't a giveaway, it's just a fork: everybody has the same number of coins as they had before, and the chain continues from there in a different direction. Usually the Fork creators give themselves a lot more coins (instant profit!).

If you want to know how real airdrops handle it, have a look at Byteball or Bitcore.
