it will never happen, doge coin is only a good coin for transfering without big fees
That's a pretty major use? People can transfer millions of dollars worth of coins for under 1 cent, that's pretty remarkable in my opinion.
Not really, because you have to sell your Doge for Bitcoins. And exchanges usually charge around 0,2% for that, which means that it's cheaper to just use Bitcoins for transfers for transactions that are larger than around 5 to 10k USD.
