Hey is it worth to use a expensive Scratchcard? Or more profit if I sell it? I speak of the Golden Glory Scratchcard .
You can get achievements for using it but if it's sP you care about, sell the scratchcard
the Golden Glory is very likely but not certain to get a jackpot. Jackpots from scratchcards average two to three millions of sP. They vary from .7 to 4.3MsP in my experience.
This card is about to become cheaper because it is being given by a monthly. The Achievement it is for is somewhat difficult to get, as Achievements go and this is why the price difference. Folks only need to get the Achievement once though.
Sell it now, then when they become cheaper in the following months, use it for the Achievement later.
