How to show a child how to earn money by playing games? I thought about this question when my son wanted to make a serious purchase, but could not earn at least half the cost of the purchase. Then I started looking for options, and found an online game Plants vs Undead in which I not only do not spend my own money, but I will be paid, and not anything and cryptocurrency. And now the value of such a currency will be confirmed anywhere. So I got out of the situation and helped the kid earn his first money.
