One thing to be very aware of when it comes to DOGE: Liquidity - it does not have any.
Sure, the price may be X but if you want to actually sell more than pocket change then you will quickly learn that what you are actually able to sell it for is X minus 10-20%.
BTC is king because it has liquidity, if you want to buy or sell $100.000 worth then you can do so without much slippage. Try buying or selling the same amounts worth in any altcoin and you'll find that you can't without significantly moving the market. This is why DOGE price movements do not impress me.
Also.. look at #dogecoin on IRC. "OMG THERE IS A 10 BTC WALL" they say.. as if 10 BTC is any amount worth caring about.
