I thought I would never buy those new stickers because it costs too much for me. But earlier, I just found myself clicking on the Checkout button. I don't know. Maybe I just can't resist these penguins. Haha. Also, I did it for an experiment which is regarding the new update - our all time revenue shown right before the gems.
I guess you'll be seeing more of Penguins sticker from me starting today. 0.0046 mBTC should not be wasted. Hahaha!
