Lets see if that 9 BTC wall is gonna hold

Edit: Aaand it's gone...

And:

How much can 1TH Asic mine pre day ? How to calculate that ?

Just take the PPC mining calc on coinwarz.com and input the statistics currently for BTCD. I.E. The reward, price, diff, fee, etc...

it shows something like $1,366 montly !!! (i didnt change block reward field, cant find out how much is it...)

which sha256 coin is more profitable than btc to mine with asics right now ?

All you have to do is take nethash, find out how many blocks were found in the last 24 hours, and divide the total coins by the total TH/ses. That will tell you estimated how many BTCD a TH/s will earn per day.

Usually, I just scrap the extra variables and look at it from this angle... to be equal to mining BTC...

In this case... 2940 blocks have been mined roughly in the last 24 hours... so lets start with 2940 * 80 BTCD = 235200 BTCD

235200 / 1250 TH/s = 188.16 BTCD per day. That means, in order for it to be equal to BTC earnings, it has to be the average earnings per TH/s per day (.029 BTC) divided by 188.16 = .00015412 BTC per coin.

This however, is not accurate because of difficulty increase in the last 24 hours... instead... you really have to focus on what the specs are supposed to be in real time...

SO that is 115200 coins minted per day per spec... 115200 / 1250 = 92.16 BTCD and then break that down again .029 / 92.16 = .00031467 per BTCD which is indeed closer to target.

The problem with this is... nethash is displayed as a function of difficulty when pulled from the console... and not a real showing of the total hashpower on the coin, so as I typed this... it now shows 1500 TH/s.

115200 / 1500 = 76.8 and .029 / 76.8 = .00037760 per BTCD. Now... take into consideration what a RENTAL cost is... if you are lucky you can get one at .04 BTC per TH/s per day... there are lower but they get snaked way too quickly for the average person right now. That is...

.04 / 76.8 = .00052083 per BTCD... which is right on the money where we sit.
