Well, best credit earner is premium tank that fits your playstyle

Here are some tanks = t49 (I usually get 20-27k credits per wining battle after all extra costs) , pz 3/4 ( good credit grinder aswell (inHopefully it will help you get credits fast but still premiums are best money makers

The Lowe is the best credit earner overall capable of making $100k even while fully-loaded and firing some prammo (which you rarely need)! But it is nowhere near the top of the Tier 8 tanks like the Victory is in 6- in fact the Lowe just gets ripped

The main money makers are the tier 8 premiums; a good round in one of those can clear 100,000 credits (gross; typically about 60-80,000 net, depending on ammo and repair costs) on a premium account

T34 is going to be buffed in 8
