Yes,you're right,like i do use my normal mobile data subscriptions to run all these platforms because i don't have any other option.Make use of WLAN is the best way to profit out of those paying platforms.Okay, i know its a certified money making app. But the usage of mobile data isn't worth it for those still using wired network to connect to it. It is best suited on a WLAN, with an unlimited subscription to go with.
