Introduction
BTC is the abbreviation of Bitcoin, The concept was originally proposed by Nakamoto Satoshi on November 1, 2008, and was officially born on January 3, 2009. BTC is a virtual encrypted digital currency in the form of P2P with a total issued size of 21 million. The Bitcoin network will release a certain amount of bitcoin every 10 minutes, and it is expected that the number of bitcoins will reach the upper limit in 2140.
Bitcoin does not rely on a specific currency institution for distribution. It is generated by a large number of calculations according to a specific algorithm. The Bitcoin economy uses a distributed database of nodes in the entire P2P network to confirm and record all transaction behaviors, and uses cryptographic design to ensure the safety of all aspects of currency circulation. The decentralization of P2P and the algorithm itself ensure that the currency cannot be manipulated by mass-produced bitcoins. Cryptographic based design allows Bitcoin to be transferred or paid only by the actual owner. This also ensures the anonymity of currency ownership and circulation transactions. The biggest difference between Bitcoin and other virtual currencies is that their total quantity is very limited and extremely scarce. Therefore, Bitcoin is also called "digital gold" by investors.

Introduction
Ether (ETH) is a digital token of Ethereum, considered "bitcoin version 2.0", using the blockchain technology "Ethereum" different from Bitcoin. Ethereum is currently the most widely used public blockchain system supporting full application development to support a wide range of advanced features, allowing anyone to issue tokens and to write smart protocols, decentralized exchanges and more. Specifically, Ethereum uses a Turing-complete scripting language that is similar to assembly language, allowing code to be written for what you want to achieve through a mechanism called a "smart contract." ETH is essentially a blockchain + smart contract. A contract is like an automatic agent living in an Ethereum system. Whenever a transaction is received, the contract runs a specific piece of code that can modify the data store or send the transaction within the contract.
