It seems like PB mining has the lowest btc/gh/s ratio and offer 5 year mining contracts so if you want a set it and forget it solution, here you go. I do not recommend the 5 year contract unless you plan on adding hash rate because xxx hash doesn't stay relevant long in the game of mining...
Some people look at the 5 year contract from PBMining and are turned off by it. I don't see why though. You make
a single payment at the time of purchase and the GHs are yours for 5 years. There are no other fees. And at the end of 5 years, your contract is done and you walk away.
Besides, the vast majority of your return will come in the first year. And unless the BTC exchange rate increases dramatically, you might not want to even bother collecting the the last few satoshis that you will collect in the last couple of years of the contract, lol.
So just think of it as a one year contract when you do your computations. It's still a pretty good deal.
