Wintub is the chinese app and its big scam be aware. China uploaded so many app like this tiktub, money wall etc. Those app give us opportunity to watch video and earn but reality is they don’t pay. I have experience about this, I used Wintub and I watched so many videos, ads to get payout. But i don’t receive any money. They only use us to make their profit. So, I request you don’t use this app who claim big moneys by just watching videos because its never pay you.
