Lately i have been trying to accumulate Ark. I think Proof of Staking and Delegated Proof of Staking are both very good concepts for cryptocurrencies and will beat Proof of Work in the future (with more adoption and scalability, and less to worry about centralization)
Maybe your thinking is the same as me about Ark, from the beginning until now I still see Ark very good in their trade, because I see until now their price is still very good there, that is what makes me survive in ark trade.
