Seriously, do you not understand the Digital Currency markets at all and how people generally value a coin?
Do some research dude before you waste any more time / money.
I'm trying to help.
Here, let me explain it so you don't have end up reading some garbage on a link you shouldn't have clicked in the google results.
Some very ROUGH figures for you
From http://emo.crypto-hamsters.com/index.php?page=statistics&action=pool
1Mh/s = 2m coins per day
1MH/s costs around $2 a day in electric.
Current price of Emoti = 10 litoshi
2m x 10 litoshi = 0.2 LTC per day = $3.3 giving $1.3 profit.
If it reaches EMO/BTC then the minimum incoming per day would be
2m EMO x 1sat = 0.02BTC = $12 per day. No one's going to pay that so why could MintPal waste their time adding it?
Sure, if EMO can get the net hashrate up to 100Ghs then the coins per day for each person may get low enough where that's realistic, but that's a LONG way off and it would STILL trade in LTC anyway.
Heck, EMO/TIPS is more likely than EMO/BTC
