Dash and ZEC are valued very low compared to their Realized Cap, both are underwater about 70% today, compared to average amount invested (MVRV = 0.3). Both have a valuable business model paying dev's and marketing with piece of inflation, but Dash revealed low ethics of it's founder Evan Dufield by doing instamine at launch and being dishonest about it up until today. While most coins went up from their low in Dec 2018 or worst case sideways, ZEC went down, likely because of controversial but necessary decision to transform business model from temporary to an indefinite and sustainable one. The only negative I see with ZEC is the philosphy of it's founder Zooko to not want to see Zcash being adopted in black market, which is an advantage for Monero, but unlike Monero, Zcash has a positive culture not spreading FUD about competitors and even better privacy tech as Monero. Since ZEC is a coin I may actually use in future, planning to pick some up if we correct to $160B Total Market Cap/ $6k $BTC.
