1.

It's about 37 yuan

let me first introce the reward mechanism of bitcoin system

bitcoin can basically dig out a block every 10 minutes through system settings. The reward for each block is given to the miners who dig out the block. The miner who digs out the block is called the block miner. The block miner will record the legal transactions in the bitcoin network to the blockchain, so that the miner can receive the service charge for bookkeeping

there are two parts in the reward for the block Miner: one part is the reward given by the system, which is called coinbase reward (also known as system issuance reward), the other part is the reward for bookkeeping, which is called miner's fee. The coinbase reward started with 50 bitcoins. For every integral multiple of 210000 blocks, the coinbase reward will be halved. This is what we often hear about bitcoin mining reward halved in four years

at the present stage, the reward of coinbase is 12.5 bitcoins. At the present stage, the average transaction miner fee received by miners for digging out a block is about 0.1 bitcoin (not fixed), that is to say, the average reward received by miners for digging out a block is about 12.6 bitcoin

about 99% of miners' rewards come from the system's coinbase rewards. According to the bitcoin system, one block can be g out every 10 minutes on average. The number of new blocks that can be g out in one day is 144 (60 * 24 / 10 = 144). At present, the number of bitcoins that can be g out every day is 1800btc (144 * 12.5btc = 1800btc). With the miner's fee of about 0.1btc per block, the total reward for all miners in one day is about 1814.4btc

2. Renren mine can excavate with a 0.04 bitcoin deposit, without paying any rental fee. The deposit will be refunded as soon as it rents. So the zero cost is true. How can Renren mine make a profit? In fact, the electricity cost of Renren mine is very low, only 20 cents more per kilowatt hour. The biggest cost of digging bitcoin is electricity. Renren mine takes a part of the total income of mining machinery, which is his profit, But even if a part is taken away, the yield is several times higher than that of traditional deposits.

3. Bitcoin is nothing more than an exhaustive algorithm. The more threads, the better the CPU effect. But it mainly depends on the performance of the graphics card, especially AMD's graphics card. However, 24 can't dig out a bitcoin.

4. What else do you need to set? My two computers, the power supply is overclocking three a 6, can't two computers are power problem? In addition, when I dig p2pool, the mining speed of the two graphics cards is normal, and each one is more than 100 mhash / s. I may have found the reason myself. I just chose btcguild (Florida, USA) [btcguild (any) was the first choice] on the server of guiminer, and the two graphics cards returned to normal. Contact the problem announced by btcguild two days ago, which can explain why btcguild server was attacked.

5. Your efficiency is too low. The speed I calculated with the graphics card is 226mhash / s, and the current ASIC device can reach 60g / s, so it seems that your speed will not contribute.

6. Speculation, that's all. Everyone who participated knew that it was a fighting game, but people kept making up reasons to deceive themselves. Bitcoin mining machine is just a program calculation, don't think too much, as long as you know, the longer it takes, the harder it is to dig.

7. Mining and mining; Collection of herbs; The proficiencies of planting three skills to level 10 are the same:
2835
it only requires a lot of tribute. To upgrade one skill to level 10 requires 3850 tribute points, and to upgrade three skills to level 10 requires 11550 tribute points.
but these tribute points are not easy to get. You can get 25 tribute points only after doing one round of expansion task Proficiency requirements:
Level 1, level 2, level 3, level 4, level 5, level 6, level 7, level 8, level 9, level 10

Second, the cost of money and contribution requirements

grade 1 Requires 25 silver (cooking, pharmacy, mining Level 2 needs 50 silver
Level 3 needs 1 gold
Level 4 needs 2 gold
Level 5 needs 4 gold
Level 6 needs 6 gold, 40 silver, 100 tribute, 55652 experience
Level 7 needs 12 gold, 80 silver, 250 tribute, 82028 experience
level 8 needs 25 gold, 60 silver, 500 tribute, 120904 experience
Level 9 needs 51 gold, 20 silver, 1000 tribute, 178205 experience
level 10 needs 102 gold, 40 silver Experience of silver 2000 helping tribute 262663

8. I don't know anything about playing around. It's very difficult to mine BTC now

9. I have three cards! In addition, after the 11.11 driver is installed, the accessory prompt becomes 5870 ~! Are you the same? After installing the 11.11 driver, the problem is even more serious. Open the mining software to prompt an error. Open the gpu-z detection to prompt that there is no OpenGL driver. Brother, where did you download your 11.11?
