WG had a very successful New Year event, because they made a ton of money. Lucky players got the Type 59, just 37,138 lucky ones on the EU server.

If you’ve been playing WOT for a long time and have everything researched, there’s a chance you don’t need any tanks other than tier X, so you can use this New Year special to make some credits. First you need to reach level 7 festive atmosphere. I’ve bought tanks tier 2-7 and sold them immediately for a nice profit. Tier 2-5 are 100% discounted, tier 6 has 80% and tier 7 has 60% discount. Tier 8 has 50% discount, so there’s no profit bcs you’re selling it for a half of the price.
