Currency changes suggestion

When the summer games started I really wanted to get Mercy's skin but I didn't got it and I don't have enough money to buy it (I 'm missing only 40 credits) and the only way to get money is by getting duplicates or money from lootbox but now you don't get duplicates that much. Am I the only one thinks that blizzard should change the currency system so you get money per win or something like that?
