Doge is the veritable pump-and-dump. Look at how many threads have been started in the last couple weeks pumping it. Then look at how the price skyrocketed only to fall on its face, twice!
Get into quark until btc38.com offers it at which time it will skyrocket just like all the other coins that were offered by btc38.com. You will greatly improve your investment.
I'm a noob, but I gather the price jumps are mostly caused by those auto-mining pools, which will mine whatever is most profitable atm and so artificially push the coin beyond it's "natural" growth. My guess is, that once the dogecoin's block rewards are halved twice or more though, the price will steadily and permanently rise. Aren't we still in the early days of the doge?
