Dash was the mix of both features.
"Was" because I think it kinda lost its identity when regulators started clamping down on privacy coins and some centralized exchanges started delisting them. Dash has been one of those who said they're not as private as everyone thinks and explained that it's as transparent as Bitcoin. The privacy feature is just an option for users.
Maybe they even lost their integrity to a lot of investors when they came out and did a 180 degree.
DASH is one of oldest altcoins and it got great success in 2017 and 2018 bull run after that the altcoin has never been able to reclaim their all time high in 2018. It had some great rallies in 2019 and 2020 but its performance can not be compared to Ethereum or Monero, other two big altcoins in 2018 bull run.
I believe one of disadvantages for DASH coin is its reward structures to stakers and masternode owners that is unfair and many people complain about that. Moreover, it had some attacks together with other privacy coins recent years. People are still careful with privacy coins but Monero is an exception, it got great rise in 2020 bull run.
DASH revoked its design for privacy transactions to avoid further attack on it but I don't know it is good or bad response from their team. So far, it looks to cause a bad journey for DASH. Price can not grow up in last three years.
