It seems I will have to try it out and see how it goes for a week.I see your point friend, to me this doesn't cost me anything much because I always use 7 minutes and less than 10mb of data daily over there. But as you said, it still may not worth your time.
The payment is to please. My two withdrawals l made l sent them to my binance bitcoin wallet. A friend too had his withdrawal to his trust wallet without any fee. So you can choose to withdraw to any wallet of your choice.
Like you pointed out .It's only 5 minutes and same times and data we sometimes spend on social media doing gossips and all with people's pictures and video and we even use more data on such so,adding this to the pool of mini earnings might not be that bad.
