with a current rate basic calculator. one of those 222MH minors will get you 7-8$ a year.....................................
So you decide if it's worth it..
at todays cost.rate your 10 years to break even..
These sold for 14$ at launch so the current boom has drivin cost up for the idiots on ebay.
so.. No.
well they did not sell for 14$ at launch they sold for 250$ in april
and they mine at 333mh not 222mh.
but the rest is true they are not worth the prices people are asking. in fact I purchased many as low as $6.90 then the boom hit and the price on them went nuts.
It is really hard to get gh power cheaply unless you spend serious money. he could buy some here
https://bitcointalk.org/index.php?topic=328135.msg3839917#msg38399171 share is 41 mh 100 shares are 4-4.1 gh just about .135 to .140 btc
which is about 133 usd to 138 usd.
this may be the best mining contract he can get. as it is lifetime (1-2 years) as long as it hashes in the black.
if he buys today he gets 1gh for about 34 usd . no work just watch the coins come in.
