Thanks for your precious suggestion. 
I think Doge is SHA256 type ency. In terms of investment what i calculated is if I have to invest 35 K the maximum SHA256 hashes 15MH/s which on the other hand is not too profitable also in the worst case scenario i.e sell it for 2nd hand. On the Other hand Using 2 Nos. R9 270X and Overclock them to meet 1200 KH/s (Scrypt) and mine LTC is profitable.
Since the difficulty of BTC is Higher than LTC.
Please suggest . I need your expert Advice.
