1. 
in terms of cloth storage and mining, I recommend Heshu hardware wallet and jiajiabao intelligent home miner. The core advantage of the proct is safety
take sum hardware wallet as an example. The advantages of sum hardware wallet are as follows:
1. The private key seed is encrypted layer by layer, physically isolated and never touched the Internet.
firstly, when creating the wallet, the seed password is generated and stored in the local encryption chip, and the 10 bit payment password is required
then, the transaction is made in the wallet. At this time, the user needs to enter the payment password to obtain the private key to digitally sign the transaction, and the transaction is completed. In addition, the private key seed is permanently stored in the chip, which is physically isolated and never touches the Internet. There is no need to worry about my password being stolen by hackers
Second, the bank system verifies the financial level motherboard and encryption chip
uses the bank system to verify the financial level motherboard, and the private key seed is stored in the chip. If the proct is stolen or lost, and destroyed by malicious violence, the chip will trigger a self destruct circuit, and immediately permanently and irrecoverably delete all the information in the area
Third, it supports the withdrawal of global
bitcoin ATM, which is convenient and fast
the reason why digital assets attract the attention of many fields in the world is that it is creating a global fast circulation, and the larger the circulation field is, the wider the scope is, and the higher its use value is. The core of digital assets is the medium it acts on among currencies. The Heshu wallet has built-in many mainstream exchanges in the world. It can trade digital assets anytime and anywhere. With one machine in hand, it can walk around the world without worry, and no longer have to worry about exchanging foreign currency
Different from conventional digital wallets, multi signature wallets need the authorization of multiple key holders to transfer
digital currency, so the security of multi signature wallets is higher. Ordinary Wallet: a wants to transfer a bitcoin to X. A only needs his signature (using the private key) to complete the transaction. Sum Wallet: if a wants to transfer a bitcoin to x, a multi signature verification is set (at least two signatures of Abc3 indivials are required to transfer the money), then a needs B or C to complete the signature (using the private key) when a wants to transfer the money to X. I hope I can help you. Thank you

5. The bootcfg command with the following parameters is only available when using the recovery console. Bootcfg commands with different parameters can be used at the command prompt. Usage: bootcfg / default sets the default boot entry. Bootcfg / add adds a Windows installation to the boot list. Bootcfg / rebuild repeats the entire windows installation process and allows the user to choose what to add. Note: before using bootcfg / rebuild, the boot.ini file should be backed up by bootcfg / command. Bootcfg / scan scans all disks used for windows installation and displays the results. Note: These results are stored statically and used in this session. If the disk configuration changes ring this session, in order to get an updated scan, you must first restart the computer and then scan the disk again. Bootcfg / list lists the existing entries in the boot list. Bootcfg / disableredirect disable redirection in bootloader. Bootcfg / redirect [portbaudrrate] | [usebiossettings] enables redirection through specified configuration in bootloader. Example: bootcfg / redirect COM1 115200 bootcfg / redirect usebiosettings HKDSK creates and displays a disk status report. The CHKDSK command also lists and corrects errors on disk. The CHKDSK command with the following parameters is only available when using the recovery console. CHKDSK commands with different parameters can be used at the command prompt.

Drive: Specifies the drive to CHKDSK check/ P perform a thorough inspection even if the drive is not in the scope of CHKDSK's inspection. This parameter does not make any changes to the drive/ R find the bad sector and recover the readable information. The / P parameter is implied. Note that the CHKDSK command requires the autochk. EXE file. If it is not available in the startup directory (default is 92;%) systemroot%\ System 32) and will try to find it on the windows installation CD.

Without any parameters, the Diskpart command will start the windows character mode version of Diskpart/ Add creates a new partition/ Delete to delete an existing partition. device_ Name the device to create or delete the partition. The device name can be obtained from the output of the map command. For example, device name: &# 92; Device\ HardDisk0 drive_ Name the partition to be deleted represented by the drive letter. Only used with / delete. Here is an example of a drive name: D: partition_ Name the partition to be deleted represented by the partition name. Can replace drive_ Name. Only used with / delete. The following is an example of partition names: &; Device\ HardDisk0\ Partition 1 size the size of the partition to be created, in megabytes (MB). Only used with / add. In the following example, the partition will be deleted: Diskpart / delete & # 92; Device\ HardDisk0\ Partition3 Diskpart / delete F: in the following example, a 20 MB partition will be added to the hard disk: Diskpart / add & # 92; Device\ Harddisk0 20 fixboot writes a new partition boot sector to the system partition.

The following is an example of arc device name: multi (0) disk (0) rdisk (0) partition (1) the equivalent device name is: &# 92; Device\ HardDisk0\ In the partition 1 example, the physical device name is mapped to a drive letter using arc device name: Map arc. Note that if arc parameter is not used, the map command displays the device name. The map command also shows the type of file system and the size (MB) of each disk[ Last edited by on 2003-11-2 at 11:17] attrib changes the attributes of a single file or directory.
