The Story of the Gold Box
The community heard of the appearance of an unusual box with crystals on December 3rd, 2009. It was announced in the Tanki Online blog, that on several maps, the Gold Box would appear once the battle fund reached a set number of crystals. The Gold Box instantly became the main topic of discussion in chats and in the forum. Tankmen were sharing opinions and ideas for days. The lucky ones were posting screenshots as proof of the fact that they caught a Gold Box. Over time, people started to understand when and where Gold Boxes would fall.
Originally the box contained 1000 crystals. Back before the economy update, this was a significant amount (worth 10,000 crystals in the current economic system), especially for the lower ranks, and those who managed to get a gold box were extremely happy. However, there were players, mostly buyers, who wanted the value of the box to be lowered. The main argument was that, for the game economy of the time, 1000 crystals were a lot, so why should one buy crystals if he or she can just catch Gold Boxes?
The 1000 Gold Box only lasted a week. On December 11 2009, developers decreased its value to 100 crystals.
