I have seen similar threads quite a few times here. I don't know why everyone is focusing on the unit price, when market capitalization gives a much better measurement. For example, XRP is having an unit price of $0.19, but its market cap is $9 billion. Therefore the potential returns can be low. On the other hand, ZEC as one of the more promising coins. It is having an unit price of $47 per coin, but a market cap of only $430 million.
