I don't have much knowledge about Zil. I just know that it rose incredibly fast some time ago. If I were you I would mostly invest in TRX and would invest some in SXP also. But I wouldn't like to affect you too much, it's your choice in the end. 
Yes, everyone has the right to give good advice to others and everyone also has no right to follow suggestions from others because in the end everyone has to choose the choice according to his own heart.
