2) after buy Magic will get a new pop up window "Use Magic". In the top option leave it as "Gold Coins",
a) the next you choose how many would like to give away (minimum 10 GC)
You set a total summ of points in a Red Envelope:
"Hidec Credits"=200 GC (for example)
b) The total summ can be divided into small chunks:
"Credits per part"=20 GC (for example)
с) each chunk can be buried :( by each your space visitors.
That is, in this case 200:20=10 people (visitors) will be able to receive 20 GC as a gift.
As a result, you have minus 220 GC.
