Hi regmac & aasisharma,
I appreciate your feedback on this ... and you're certainly not the only ones to feel this way about your blogs or websites.
However, if you look at the maths itself, and say you were offered 20 times your monthly earnings ... Wouldn't you like to have all that money now in one lump sum!
The other thing to note is that your monthly revenue may be increasing but who's to say it will keep on increasing. What if your website loses it's rankings for certain keywords and traffic to the site dries up?
These sort of things can easily happen over a two year timespan. Aren't you better off to simply take the money now instead of waiting two years for that return on investment (which may or may not pay out)?
As the saying goes ... "A bird in the hand is better than two in the bush".
That's the way I look at it

Cheers,
Tony
