It will be very difficulty to find btc mining profitable at this stage, no matter you buy hardware now, make a pre-order on hardware or buy some cloud hashrate...

A black averages ~10 minutes So 2016*10=20160 Minutes 3360 Hours 140 Days That doesnt Sound right but thats the math for the numbers you just gave

Check out Varinvmin, BSVM and APG1 at cryptostocks.com
It's better than buying gh/s contracts, because they will reinvest part of the earnings in new hardware, so the value won't go down.

http://www.pbmining.com  is one of the best posted on this forum, they pay out on schedule.   Downside :  they're down.  Some website functions are available but there is no buy in ... and it's starting to look bad for buy-ins at lower GH, as they are limited in supply.

https://bit-mining.co looks interestingish... I have only -just- seen them and have no experience with their service yet.

good sources dry up fast... scammers abound with all kinds of strategies.  DOGE is starting to look better ALL the time.

If the odds are good :  the goods are odd.

I'm going to toss out a vote for pbminer, being that they change their prices after difficulty changes and offer up 5 year contracts instead of just 12 months.

It should be 336 hours (14 days).
But, as the network hashrate is increasing, we don't need 10 minutes (on average) to find a block, so difficulty adjustment happens every 12-13 days instead.

what is the best pool?(according to chart: paypershare is best?)

Pay per share (PPS) is indeed not a pool, but a payment scheme.

PPS is best in terms of lowest variance, but the % fee is higher.
It may be better to use PPLNS or DGM (higher expected payment due to lower % fee).

If you're renting, PPS is better though. You don't want variance when you are dealing with a set amount of time like an hour or a day.

Unless you are renting hashrate for just a day.
If you join a big pool like btcguild, the pool luck wouldn't vary that much with PPLNS.

For reference only: btcguild pool luck at this very moment.
Approximate Pool Luck* (24H / 3D / 1W / 2W / 1M): 92.069% / 101.504% / 98.734% / 102.433% / 101.802%

Though the average luck is at 98.7% for 1-week, you still get more btc using PPLNS than PPS.
