For those who are interested in micro earning sites I have news here.
There is a website cryptoperhour.com. Here you have to perform micro tasks like posting in face book, twitter, You tube, Instagram etc and from that you will earn small amounts of USD.
Later you can withdraw them in Bitcoin. The minimum withdrawal is 5 USD (equivalent amount in BTC).
It doesn't take much time to perform the tasks. You can give it a try if you want and consider it as another passive earning source.

You know that the next block fee for a BTC transaction is over $4? https://bitcoinfees.cash/
