There is a constant hope that Monero will suddently moon 10x or the like, most other cryptos do from time to time. Consider that as a sign of health, not the opposite. Monero has a steady organic appreciation decoupled from the existing financial system. Under normal circumstances a yearly ROI of 165% would be considered to be pretty amazing. Sudden spikes of 1500% in a crypto that no one is using (zcash) is not just suspicious, it's direct manipulation (don't fall for their trickery).
