Dash use to be a top coin rivaling with bitcoin. Not its a sinking ship.
Dash is one among the top ranked coins but it never happen that it become in the top like Bitcoin and Ethereum but if you will just be fair then you could see that not only Dash is sinking but most of the Altcoins and Bitcoin too. Dash is a good coin but it just happen that the people are selling it too because of the on going bearish market. Hopefully, the bearish market will be over soon as we are expecting a bullish mode before this year would end.
