Im actually surprised RingCT hasn't had any effect on price, but I'm in for long-term investment anyways.
I could definitely see a price of $50 to $100 in a few years from now which would be a great return on your investment, even if you bought today.
If Bitcoin can hit $1000 I don't see any reason that coins like Monero and Ethereum couldn't hit that price point.
Monero has already been over $18 USD just recently, so a 3 times increase would not be ridiculous and put it over $50. So, I think it would be very likely that we could see that mark in the next month or just a few weeks. Especially with the volatility that we've been seeing recently.
