Yes, you need to purchase ad-packs to earn. But the amount you spend from your pocket doesn't have to be a large amount as you have the option to repurchase internally. I know people who are earning 1 BTC everyday. I myself am earning 0.15 BTC everyday. I don't think there is any other platform where you can earn so much so fast with such little effort. You need to have apply a well planned strategy though.
