As with everything regarding oscillations on free markets, it would be naive of me to try to pinpoint a cause (or causes) in cases like this, especially for the absurdly fast price increase. All we can do is a pragmatic analysis of what happened: the coin's price increased from under 50 to over 2000 satoshi too fast, something which would inevitably end up leading to a massive price correction and profit taking. Anyone who has followed bitcoin from the beginning saw that happen lots of times.
What people fail to notice is that, even with DGB at 500 satoshi (or even lower), that still means huge profits for everyone who was mining or holding the coin more than 3 months ago when the price went as low as 19 satoshi. Hell, if you had bought the coin at 19 satoshi, when it reached 190 you'd already have made a profit of 10x! The only people whining are the greedy ones who never supported DGB and only showed up here AFTER the price started rising so fast, hoping to make a quick buck. Real supporters and savvy, level-headed investors won't be bothered by bubbles or heavy oscillations happening within a couple weeks span.
a lot of newcomer got into this at 2100satoshi, i really dont like the way we made profit is someone had to be eat each other
