Benefit: Connection between Astrology and Fortune-Telling
In the Name of Allāh, the Ever Merciful, the Bestower of Mercy
Answer: The connection between astrology and fortune-telling is that both of them are based upon falsehood, deception, unlawfully taking the wealth of the people (theft), causing depression and sorrow and the likes of this. As for their dangers upon the Muslims, then you would have to look at how widespread it is amongst the people. It could be that in some countries there are no general signs of astrology, and the people do not rely on or believe in it but fortune-telling is widespread amongst them, which makes it (fortune-telling) worse (than astrology), and vice versa. But in general, fortune-telling is worse.
