500btc

2.

The total number of bitcoins is 21 million

in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

monetary characteristics

1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom

2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution

5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay

6. Cross platform Mining: users can explore the computing power of different hardware on many platforms

3. Spend money to repair mobile phone shop brush it!

4. BTC's Chinese name is bitcoin. You're here to water, aren't you? What's your problem????

5. " Point difference & quot; When the exchange rate changes, the difference between the fluctuation of points is & quot; Point difference & quot;. For example, when USDJPY changes from 120.00 to 121.00, 121.00-120.00 = 1.00 yen, and the spread is 100 points. When GBPUSD is changed from 1.0000 to 0.9800, the point difference is 200 points (the corresponding point of 0.0001 US dollar is 1 point, which depends on several significant digits after the decimal point)

the transaction fees of domestic trading platforms are generally free, so there is no point difference problem.

6. The e-invoice system does not support void operation.
in case of return or error in issuing e-invoice, the drawer should write down the amount by issuing a red ink invoice. The red ink invoice issued by e-invoice should be consistent with the corresponding logistics and capital flow information.

7. For example, the service life of each computer is 3500 yuan, the net output value is 500, and the annual depreciation is (3500-500) / 5

Troubleshooting:
1. I went into the 3.5x folder in patch, but all the three files in it ran, and then the screen went black.
A: close all your plug-ins, first run 1.50 core irshell, and then run 3.5x & # 92; The eboot.pbp file under btcnfpatch

2. Does it support PSP2000
A: the author said that I support it. I don't have PSP2000... I can't test it.

3. Can I do a tutorial for video output
A: because the video output is similar to 3.7, and Jiangnan Sisi has done a good tutorial
please refer to http://www.cngba.com/thread-17026267-1-1.html

3. Why can't my PSP2000 run 150 core irshell
A: PSP2000 doesn't support 150 core irshell, please delete PSP & # 92; GAME150 folder

4. What's wrong with broken icons
A: please use__ SCE__ And%__ SCE__ To hide the files in the damaged GAME150

5. About the PC keyboard and handle mapping function (turn to Jiangnan 44)
A: after testing, you can play PSP games with the computer keyboard and handle at the same time. First, install the handle correctly in the system (the Logitech al action handle I use is free of
driver, and the system can automatically identify it), then open the keyboard and handle mapping function in irshell to control the PSP. It's just that there are differences in key positions, which should be adapted to
. Irshell can be set according to the following figure:

at present, this version does not provide the option of Custom PC handle key
but I put it in 92; RemoteJoy4iRS\ MS_ ROOT\ Joy in the directory_ 1. The map file is opened with a text editor and can be modified. Different brands and models of PC
handle keys are different, so interested friends can try to modify it by themselves

the mapped keys of PC keyboard are as follows:

6. About the application of irshell file association
this is similar to the file association of windows system. For example, if your computer has office 2003 installed, you double-click the *. Doc file, Word 2003 will run automatically
