Calculation difficulty adjustment

1. Is the difficulty of the whole network computing increased

2. In January 2013, Avalon released the 60g / s miner specification and accepted the booking. In January 2013, Avalon delivered the world's first commercial bitcoin ASIC miner, and the core developer of bitcoin network, Jeff
garzik, was fortunate to be the owner of the first commercial ASIC miner.
the most difficult mining problem was 0, and the computing power was about 2p at the beginning of 2013, and now it has reached 100p

3. When the mining income of BCC is lower than that of BTC, the computing power will be reced and the speed of block proction will be slower. If the interval between the past six blocks is more than 12 hours, it will rece the difficulty by 20% in each block. It is precisely because of this emergency difficulty adjustment mechanism that the difficulty of BCC will drop greatly sometimes.

4. Whether m3 can generate value for you depends on your electricity cost
many free electricity miners use m3 and pay back in two months
50 cents per kilowatt hour miners use m3, and their daily income is not enough to pay the electricity bill.

5. I saw it on a forum and said it was two hours, but the details are not clear

6. Hello, you can't buy a hoe for the mobile version of legend of hot blood. Mining method, click the calendar in the upper right corner of the mobile & gt; Daily activities & gt; Slide up the screen to select mine, and click go. It will automatically find the way to find the foreman, transmit it to the mining map, enter the mining map, and a hoe sign will appear in the lower right corner of the mobile phone. When the character is close to the wall, click the sign to automatically mine. It can only dig for half an hour every day, and it will be automatically transmitted to the foreman after half an hour. The mining map is only transmitted to the foreman.

7. Format fm1=new DecimalFormat("#,####. 00");< br />double num1=12345.678;< br />fm1.format(num1);< br/>

8. A. When chemical reaction occurs, the more metal atoms lose electrons, the stronger rection ability is not necessarily. For example, the property of gold: magnesium > aluminum, so a is wrong
B. the rection of metal cations does not necessarily lead to the formation of metal elements. For example, iron ions are reced to ferrous ions, so B is correct
particles with the same number of protons, such as water and neon, are not necessarily atoms of the same element, so C is wrong
D and sodium peroxide can only react with acid, belonging to peroxide, not alkaline oxide, so D is wrong.
b is selected

9. The network of service providers is awesome, but digging the money to the back is not the main driving force. After all, the difficulty is always adjusted at any time.
