VIB 2x in the last couple days.

I think the next double or more.. to 10x is Spectrecoin (XSPEC), best undervalued privacy coin.  More private than zcash/dash. 
Think it will go from $0.50 to $5.00.
That's 10x. 

Longer term, think it'll be $50. imo.  Get in before others or get missed out like vib. Get in early.
