Are you sure, that "presently PETA offers the best cloud mining investment out there" ?
Lets' do some calculations.
PETA: Price = 0.00263 BTC/GH/s, Divident = 0.00001556, 0.59% today
PBMining ( http://pbmining.com?ref=fizzly )
Price = 0.0026364 BTC/GH/s, Divident = 0.00002684, 1.02% today
... and if you are wise, you shall understand why 0.0026364 and not 0.0029
Can you trade pbmining?
I don't need trading PBMining. I know that 5 years the daily divident will be without charges, according to the "difficulty", as is today at 0.00002684 BTC/GH/s/day, according to https://bitcoinwisdom.com/bitcoin/difficulty.
With PETA I know today dividents are 0.00002107, tomorrow may be 0.00001467, may be X or Y, with incredible misterious charges (salary, hosting, ..).
Then you have to compare PETA with similar offers like CEX.io and Cryptsy Mining Contracts, you will see PETA is trading much lower than the former two.
