DRK is currently up ~500% in 20 days. I haven't thoroughly done the research prior but I am wondering what other coins have sustained these kind of gains and for how long.
KARMA has had a 2200%+ growth since April. In the Litoshi range, so not the same scale, but it has been gradual rather than the effects of a pump & dump situation. With the new announcements today it should see some additional growth as well.
