With all the hashrate DGB got in the last week, you can be sure that most of those that helped get to block 145 000 won't hold this coin. they will dump no matter the price to get back to the coins they have in their portfolio. Sad but it happens, DGB is now a multi-algo (first to switch from single algo), dev just need to continue their great work and things will keep improving.
I can only speak for myself... but as one of those who threw significant hashpower at the network to push it along in the days leading up to the switch I can assure you
I have never sold a single DGB, not now and in fact not at all in the history of the coin. I've mined a load and bought a load.... and intend to buy more. I'm still mining on scrypt with my own equipment at a significant loss, although that may come to an end soon as I am considering selling my ASICs. I'm holding for the day they are actually worth something and I can either buy directly or sell for real money, not fractions of a BTC.
