1. bitcoin core is an official client used to manage the private key of bitcoin. Having the private key of the bitcoin address means having the control right of the corresponding bitcoin. Once the private key is lost, it cannot be recovered. Therefore, it is very important to back up the wallet
the wallet file of the wallet client is the database for storing the private key of bitcoin. Both the private key and the public key are stored in the wallet.dat file of the bitcoin wallet. Keeping wallet files securely in multiple locations prevents bitcoin from being recovered in the event of an accident
wallet file location
Windows XP - C: & # 92; Documents and Settings\{ username}\ Application Data\ Bitcoin\ wallet.dat
Windows 7/8 - C:\ Users\{ username}\ AppData\ Roaming\ Bitcoin\ Wallet. Dat
Mac OS X ~ / library / Application Support / bitcoin / wallet. Dat
linux ~ /. Bitcoin / wallet. Dat
the above is the default wallet directory of bitcoin core client. If the data directory is specially set, you can search the keyword "wallet. Dat" through windows to the wallet. Dat

2. It depends on whether the wallet has the function of automatic collection. If it is not open, it can't be withdrawn. However, bitcoin cash has been born for a long time, and it can't be withdrawn
on August 1, 2018, bitcoin carried out a hard bifurcation to proce BCH. BCH is the result of community division, not a kind of bifurcated coin. BCH has its own strong community support. However, at that time, some wallets did not support BCH to collect.
3. Stored in the block folder of bitcoin wallet folder

< critical hit
class A certain probability causes 150% of the attack power & mdash; 400% of the damage. Some skills can't be dodged, some skills can only be triggered when the enemy's combat power or own combat power is lower than what percentage, and some skills can't be launched until a certain round
< percentage
class It has a certain probability to damage the enemy's current combat power percentage. Heroes with this skill are best placed in the front row. The earlier you trigger, the better. Armor can resist the damage of this ability
< recovery class
It has a certain probability to recover the combat power of your damage percentage or the combat power of the enemy. Hit damage will be resisted by armor, but recovered combat power will not count as armor. When you regain your combat power, you will ignore the enemy's armor
< four dimensional
class Increase your four dimensions, attack, defense, dodge and king
5. This problem I have encountered, I 2003 system under the wallet, found that the wallet data file is wrong! Thought it was a problem with the 2003 system! Specially modified 64 bit win7, error still! I don't know what's wrong! I feel that I have been following the upgrade of bitcoin wallet all the time! Up to now, it's 1.49M, but no matter how I make it, it's all a mistake! At first, delete all the block chains, only one wallet data file! After the update is completed, you can see that it is normal for a period of time. If you open the wallet for a long time, you will report an error again. After the error is reported, unless the reconstructed data is displayed normally for a period of time again! But still can't solve the problem! Back to the original just built wallet file, just set the password, just set up the collection address data backup out to use, the result is no problem! And all bitcoin is still there! By contrast, when using the 1.49M wallet data file, the record of the latest received bitcoin can't be written in, and then it's OK to look at the data backup file. Anyway, there are no recent transaction records, but there are so many bitcoins, so the error should be here! But I don't know how to solve this problem, I can only use the original wallet backup, fortunately, there is a 300 K backup at the beginning, otherwise it's finished! Now there is no problem, this problem has to be reported to the official!
6. This is a drawback of bitcoin. You can't delete it. You have to resynchronize after deleting it. Of course, you can use light wallet, but its security is not as good as this one
7. The wallet file downloaded from bitcoin QT client is wallet.dat, and the wallet file downloaded from multibit client is multibit.wallet. The file name, size and format of these two files are different, so how to switch? If you don't need to save the original address, send the coin directly to the multibit address
8. No backup dat file. If you delete it, you lose it.
