Is it realistic to expect a ROI of shares in scrypt miners?
A better question would be - what is a good $/KHS rate if I'm thinking of renting miner shares?
Wouldn't it be much more profitable to mine scrypt coins in a pool compared to mining BTC in a pool?
I assume you ask 3 question.
1) No
2) None
3) Yes, mining scrypt is more profitable because too many ASIC on BTC competing.
