Ok so finally I received my first payment of 0.0258. No clue why did I not get 0.035 though as I made over 50 posts but I am happy and will be trying and making more posts this week

You sure you made the 50 posts whithin the 7 days timeframe?
Perhaps some of them were considered off-topic.
I think 50 post on a week is quite easy
7 post per day = 1 post every 3.5 hours
It should be enough time to make a quality post
It's not about whether it's easy or not to make plenty of posts in 7 days.
Looking at his post history :
February 9th he made 21 posts
February 8th he made 7 posts
February 7th he made 4 posts
February 6th he made 4 posts
Look at the difference, especially February 9th.
Perhaps that's the reason for not getting paid for everything.
Posting should be done spreaded within the 7 days timeframe, and with a 21 post peak at February 9th the bot may consider them as off-topic or spam.
