my speculation about dogecoin? is just a shitcoin dont expect lot of it while this litecoin try holding some of it in 2018 expect some higher price of litecoin
Doge will be around after most other coins are dead! Because people use it to move money from exchange to exchange to save on fees.
The doge price is currently sitting on support of about 15 satoshis. The dollar price tends to be steady, which means the price in satoshis tends to move up when btc is down against the dollar, and it moves down when btc moves up against the dollar. It's good for hedging.
