随着比特币区块链数据容量越来越大，而客户端钱包数据默认安装在C盘，如果C盘不足够大的话，就需要想法将数据从C盘迁到其他盘。
With the growing capacity of Bitcoin block chain data, client wallet data is defaulted to be installed on Disk C, which, if it is not large enough, requires an idea to move the data from Disk C to other disks.
其实比特币，是通过计算机联网计算产出的，也叫做挖矿，最开始有个人电脑可以挖，不过效率比较低，而且费显卡。之后有了专门的比特币挖矿机，几百到二三十万元不等。
In fact, Bitcoin is a computer network that calculates output, also known as mining, and starts with personal computers that can be dug, but it's less efficient and expensive. Then there's a specialized bitcoin miner, which ranges from hundreds to 2.3 million dollars.
具体解决方法如下：在电脑桌面上打开“此电脑”（win10），如果是win7系统则为“我的电脑”。鼠标右击“本地磁盘c”，选择“属性”。选择常规选项卡的“磁盘清理”。
The solution is as follows: to open this computer (win10) on the desktop, and in the case of the win7 system, to " my computer ". The mouse clicks " local disk c " and selects " attributes ". Select the " disk clean " of the General tab.

3. Security, security is at the heart of Apple Pay, and when credit or debit cards are added, the actual number of the card is neither stored on the equipment nor on the Apple server.
1、硬件钱包通常比软件钱包更加安全，因为它们离线存储私钥，从而更难受到黑客攻击。一些常见的硬件钱包包括Ledger和Trezor。纸钱包：这是一种离线存储比特币的方法，它涉及将用户的私钥印在纸上，并将其保存在安全的地方。

Paper wallets: this is a way offline to store bitcoins, which involves printing the user's private keys on paper and keeping them in a safe place.
2、比特币是一种P2P形式的虚拟的加密的数字货币，它并不依靠特定的货币机构发行。比特币于2009年1月3日正式诞生，最初是由中本聪在2008年11月1日首次提出的。它是依据特定的算法，通过大量复杂的计算所产生的。
2 Bitcoin is a virtual encrypted digital currency in the form of a P2P, which does not depend on specific monetary institutions.
