The pool shows an average the last trade on the exchanges that we support which carry the coin - in the case of PIG, its Bittrex and Poloniex at the moment.
Sorry what average is 90 when last trade on poloniex is 164 and last trade on bittrex is 155 ?
anyway if for 0.00000090 the profit is 0.00087983
for 90*2=180 profit will be 0.00087983*2 = 0.00175966
this not will pay even my electricity bill
