Yes my friend, all of the details that you need to know is already there. You'll just have to click the coin and you'll see "daily income", "weekly income", "monthly income" and "yearly income" and this varies due to market conditions.
And as for ROI the percetange is indicated at the list "ROI".
1* -What does the term "MN Worth" mean in the titles?
That means minimum worth of investment for example dash, you need $160,130 to start a MN for that coin.
2* - the terms "monthly" and "yearly" is the amount that I will earn per month and per year?
Yes! that's an estimation but it can change and depends on how the market will turn into bullish.
If the market goes bull then that will increase.
