I would say yes. DSR was also my first MN and boy how do I regret it. Lost a bunch of money on it. And not because crypto is high risk, but because the dev is like his name implies, a lazy boozer.
Owning tons of DSR he manipulated everything. He is never active, it's just now that his shitty project is threatend he is back.

Swap your old DSR to GRV. You'll be happy you did.
