I think DGB is not pump and dump coin. DGB is good coin and have good technology.
DGB coin have  a good setup for gaming purpose especially with the new game coming like minecraft.
Few days ago dgb price was 2400 satoshi and the current price is 600 satoshi most of the people are  holding dgb and waiting to go up the price.

   

I think the main reason behind the dump of all altcoin is bitcoin segwit is near and because of the segwit hype peoples are doing panic sell most of them most of them are scared so that is why they are losing their patience.
