To know if a specific coin or project is worth it in terms of investment or not, we must pay particular attention to its history, Dash has been running for years and its team has never stopped updating its development. Dash is one of the so-called "privacy" coins (although a few weeks ago one of its founders made some clarifications on that aspect due to future problems with the SEC) and it has always had a good position in the market. So I think Dash is a good investment, but as I always say DYOR.
