by a look at the hash vs pacmic, it's better to go with the hash, it has a 6 roi and you can sell faster your hash at any time, just buy the whole hash of a single unit, so you can reclaim it one day if needed
i was going to invest myself because 6 months isn't that long, but no one responded about the total profit per day minus any fee, i opened a thread about it...
I purchased an s-7 in hash on the site 4860gh it unlocks in 6 days. the 18th of nov
coins where higher when I got it I paid 5.82 btc
at current price of 0.00164 I could sell 3560 which would
A: give me 5.838 coins vs the 5.82 paid
B: leave me 1300 gh that are at a cost of -0.018 btc
I would then just buy more gh from the earnings on the 1300gh
Now when the s-7 unlocks maybe gh prices change again.
Of course this is only a btc win not a usd win.
that usd gain or loss would not be known until I cash out the 1300gh
and cash out the 5.838 coins I got back.
ie I could profit 2 coins and still lose usd if coins tank next year.
