I think Dash coin should just make a huge development to be patronize and have a better number of investors once again if they wanted to regain what has been lose to their reputation as one of the top ranked altcoin. I know that Dash is really a good altcoin to invest with also I just don't think that is undervalued but instead under-develop as of the moment.
There was a time when Dash was being regarded as the best PoS coin available at the market. So a lot of people invested in it. But when the prices crashed in 2018, many of them ended up with huge losses. The other altcoins made their recovery in 2019 and 2020, but Dash didn't went up as much as these coins. Another factor was the closing of BTC-e/Wex.nz. It was a major market for Dash.
