I'm buying 21,000 BTE for 0.1 BTC
That looks reasonable, me too.
And we already have a market price!
that's not a market price. thats BID.
you need an ASK to even try to guess the market price ,
and market price is what last trade taken place at(pizza), that would be 0,0001111 BTC/BTE or 9000 BTE/BTC for easier calc.
difficulty is 64 with 60% rejects, so mining now gives you 3.143 BTE a day per MH , comparing to LTC profitability thats a minting cost of 0,0107 usd
which makes actual price of 0,01198 usd very reasonable.
but you have to know, difficulty is 64 but blocks are found at high rate so this price is a steal!! difficulty will be 256 in no time.
that is a mintage cost of 0,043USD. but i think there will be no more 60% rejects at diff256 so lets say it will be around .02 usd and 5400 BTE/BTC.
thats of course if no one else starts mining.
so i will make a 540 BTE per 0.1BTC ASK offer. now you can see your 21000 is just a BID , not a market price
