KRZYBooP:  World of Tanks economy is designed specifically to ensure players keep bouncing from tier 10 back down to the lower tiers. Most credit gains are for damage, objective completion (capturing the points). The most profitable tiers are around tier 8 while tier 10 is designed to be a little more difficult to come out positive with credits. There are also additional bonuses depending on what tank you ride in. Light tanks can gain more credits and XP for spotting damage, which is when a tank you spot is blasted by other tanks on your team. There is also the same kind of bonus to Artillery but its damage done to a stunned target. The spotting thing applies to all tanks, but light tanks get the most since that is their role in the game. With all that said lower tiers give credits but it's scaled down to what tier you are playing if it is low tier. 

Now if you are interested, but you absolutely don't have to. You can invest a bit in premium time and premium tanks. That will give you a boost in credits, XP, and training crew which learn skills to give bonuses to attributes. If you stay up to date or are active on social media there is always some free giveaway/ contest or activity to participate in that can get you consumables that boost credits, XP, and Crew XP, or premium even premium tanks.  Not sure if you have experienced a F2P business model before, but the basic rundown is a company allows players to download and play the game for free. Then offering purchases from small to large to give players a chance to "tip" or pay what they like. The F2P game does this while trying to walk the line of not offering a guaranteed win or massive advantage that you can only purchase for real money.  If you are interested in more, or joining our Discord for more help check out my signature, and welcome to World of Tanks!
