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.
1. First of all DOGE is not SHA256, it uses Scypt algo.
2. Don't mine BTC (or) LTC directly, Mine Altcoins and then convert them to BTC in the exchange.
I suggest one of the following options based on your available time, interest...etc factors.
