0.00% lets see .

my understanding is that 0.00 is is actually an interval between >-0.01; <+0.01, and even for this interval the award should have been roughly 10-12X from a statistical point of view.

The probability of it being exactly +/-0.00X with X being less than 5, rounded to 0.00 IS smaller still (about 1/25 of each other interval).

Bitcoinwisdom's percentages are rounded to two decimal places, so I think it would show 0.00 only if the actual percentage is > -0.005 and < 0.005 (because 0.005 and up would round to 0.01).

So yeah, the double reward is grossly unfair if that's what you're trying to say but there is no way I'm going to offer 2.5 BTC for it Grin

Our other cat says +1.26 to +1.5.

Personally I think it will likely be a little higher, but there aren't many slots this late in the game...

It's fun what this thread has become. Kind of like a crowded craps table  Smiley

Early cat gets the worm. Although with the hashrate still wobbling around unchanged almost halfway into the cycle - it's pretty much a gamble anyway, whether you're making an early or a late guess.

200% true

now for me will be perfect for the diff to not go up at all from this point and max .25% down Grin

isn't .25% interval a bit too big, and restrictive in number of gamblers? maybe .1% is better and also easier Wink

no one is gambling  as no one is putting up any coin.  It is a free promo.

Now if you wanted to charge a fee more players is better.

Since it is free if the number was .1     -20 to +20 is  400 players   vs 160 players under current rules.

It is hard  to keep track now.

I put together a Google sheet that, if I did it right, should track the current day's status live (you might need to go to Tools -> Script Editor -> Run -> currentBlockNumber if the data isn't current, it should then stay live. This is definitely a work-in-progress, has to be updated by hand at midnight EST for now, and I'm sure there's more than a few mistakes (our numbers are a bit off, for one), so feel free to use, criticize, or ignore.

very nice work on that google sheet.

 right now at 925 am east coast time we are at +1.16%  .

  This is a current live number and in an hour a 10ph farm could turn online for the first time thus moving the 1.16 to 2.22.  I am glad to see you took the time to give us a live number.  thanks again.

we are now at 0.72%    120 pm east coast time  that is the live number.

that sheet basically takes both www.bitcoincharts.com

and http://btc.blockr.io/charts   combines the two and make it real time.

 I just checked the google sheet and at 1036 pm we are at a real time 0.00% !!


https://bitcoinwisdom.com/bitcoin/difficulty  has  (+2.42%)  for a future prediction

I'm pretty happy with this.  It appears its going to be a small increase which considering BTC having a little increase all is fine with me.

Thanks for the kind words on the sheet - I think the moving averages are finally accurate - also I noticed the daily blocks solved that blockr.io reports are different from those that I get (though they add up the same) - I thought they used EST for their day, but I guess not.

So far the estimated difficulty change on a given day seems to move toward the 3-day moving average, but its a very small sample size.

My totally unsupported hypothesis at this point is that the final change will be somewhere between the 3 and 5 day MAs as of right now, or 2.09% to 3.63%.

Also I've been playing around with past data, trying to smooth out variance to visualize when actual large amounts of mining power came online (or went offline). It looks like, for example, about 10-15 PH went online around Feb. 15-16 or so.

It will be interesting to see what happens in the coming weeks if the recent price increase continues or at least holds where it is instead of dropping back below $250, combined with the arrival of spring in the north half of the world and the lack of consumer hardware on the market right now.

Now if I can only figure out how to automate all the things that have to be done at midnight..

I do appreciate your work on this.  As far as I know you are the only person offing a 'real' time number.

I danced around it with bitcoincharts and blockr.io  but your spread sheet nailed it.

It is a valuable number used with bitcoinwisdom and current  BTC price  it reallys helps to judge the next diff numbers

I've been watching BitcoinWisdom jumping above, below, and occasionally within my 3.76 - 4.0 guess which has been fun.  Today it is farther away (4.98 at the moment).  Still plenty of time though...

price went up so more miners went on line.

I think we are now past 280 usd a coin

Just popping in here to gloat about my soon-to-be victory!  Wink

You know, you can manipulate this contest a bit if you manage to find the last block of the period. You can adjust the block timestamp up to an hour ahead or behind the current time to actually push the difficulty a tiny bit down or up.

I'll blame it on this manipulation if I lose.

Always use escrow. OgNasty is pretty sweet.

Help me out with compiling a list of mining datacenters!

I am not sure the chances of the price being under $220 for long enough to make a difference are very good. There is only ~4.4 days left until the next adjustment and the price would need to be below that level at least a good two to three days prior to the adjustment in order for it to have any meaningful impact on the difficulty change.

I would say it is more likely that more miners will be turned back on as the price has recently increased
