Not sure where you get those numbers lol, but the continuous doge hashrate is definitely not that high. Doge has around 1/3 the network strength of LTC.
Where have you been? DOGE and LTC have had roughly the same hashrate for the past three weeks. See for yourself:
http://bitinfocharts.com/comparison/hashrate-ltc-doge.htmlThe key was 'continuous' hashrate. A huge chunk of doge's hashrate comes from auto-switchers that are only mining on probably 30% of doge blocks. This would be at least 30GH/s. When the block reward halving comes soon, all that hashing power will stop targeting doge. Compare that to LTC which goes thru much smaller variance and over much longer time periods. Doge is a joke, albeit a profitable one for the time being until interest dies off.
Doge halving comes in about 3k blocks... AKA 50hr from now.
