I've killed the 30 android mobs and I'm waiting for the icon to turn 100%.
However, I don't know what I can do with the gold coin which I can get with the reward.
So here's my question: What can you do with the gold coin from the BOSS event?

Well the gold coins can be exchanged for a title if I remember correctly. The title costs like 30 gold coins though, so you will also have to exchange the silver coins for gold if you want the gold coin choice.

Well, that's a pity. Isn't there anything else to do with the coin, such as buy things from the cash shop or something?

i think its just for a title, silver coins can be exchanged for a gold coin, i dont know how many silvers go into a gold though. but theres a title for a certain amount of gold coins too

20 silver is 1 gold...250 silvers tittle and u can get 2 tittles from gold coins each costs 30 coins

what do you get in the capsules?
