All the other campaigns in the service section are doing it why can't he? you will be motivated to post because you have an idea of your earning, if the market is going down you will likely spam to increase your post count to reach the income that you target, the market is doing great right now changing the rate to USD will do him a favor, he can always change when there is a change of market, which he always does.
