Hello,
I have a gpu rig and I have one question, is it possible minning dodgecoin and change to litecoins or bitcons?, is it more useful than minning litecoin?, thanks for all.
It is possible, and you will get better result (more revenue)...
There are different ways to do it:
1. Mine at middlecoin, and you will be able to mine the most profitable scrypt coin automatically, and the pool will exchange them for bitcoin directly.
2. Mine at multipool or other pools, and you can sell your dogecoin (or other scrypt coins) for bitcoin or litecoin yourself using an altcoin exchange
