Which altcoins can give me an easy X5 x10 in less than a month 
In my opinion, it is better to make your own research and trust your guts.
I was asking myself what to do when cryptocurrency goes down and found out that the most of the privacy coins are undervalued right now.
The best opportunity is to find a privacy-related project with a low total supply (less than 100M), that way the price will be increasing much faster.
I recently found one project called Ethereum Meta, it is related to anonymity and untraceable transaction. They have a very interesting project to build the Anonymous E-Market Place.
They are on exchanges right now, you can check their website: https://ethermeta.com/
Or even better go through their Bitcointalk thread: https://bitcointalk.org/index.php?topic=2659058.0
Agree that pricy is a sector with one of the brigtest potential but I'd say coins under 10M
100M is a huge already. A coin need 900M to make 10x, who's going to put all that money in?
