Yes they are two completely different concepts which cannot be fully compared, even though they share something in common. Monero interests me as it is a privacy coin that is secure, private and untraceable currency system. However, it has got a little to popular now which makes me started looking at other options such as Zcash, Navcoin and DeepOnion. They are the younger projects that have a lot of potential of growth and with a great entry level in terms of investments.
