1. Ethereum wallet address is your bank card number. If you forget the address, you can use the private key, mnemonic words and keystore + password to import the wallet and retrieve it. Buying and selling Ethereum is even easier. You can open an account with $100 in the realm Kingdom, and then analyze the price. Buying up or down means buying in the right direction is profitable.
2. At the top of Ethereum is DAPP. It exchanges with the smart contract layer through Web3. JS. All smart contracts run on EVM (Ethereum virtual machine) and use RPC calls. Below EVM and RPC are the four core contents of Ethereum, including: blockchain, consensus algorithm, mining and network layer. Except DAPP, all other parts are in the Ethereum client. The most popular Ethereum client is geth (go Ethereum)

Hello, according to my experience, 1. First set up the rack, then fix the graphics card, and then plug the CPU and fan, memory, SSD hard disk into the slot of the motherboard, and connect the power supply and motherboard power supply
I hope my suggestions can help you, thank you
4. Ifconfig check whether you open the network card / etc / init.d/network restart start the network card check CD / etc / sysconfig / network scripts / if there is ifcfg-eth0, if not, configure a content device = eth0 (which network card) onboot = yes bootproto = static (static IP state setting) BOOTP
5. At present, there are many digital currency wallets, some of which have good personal experience
light wallets are good for imtoken, geekwallet, kcash, Cobo, etc.
Hardware wallets are good for ledger, trezor, etc., which involve large amount of digital currency or hold for a long time. Generally, hardware wallets are recommended
big body introces these personal good light wallets
1. Imtoken:
is a mobile light wallet app, which supports Eth and Ethereum erc2.0 standard tokens (such as EOS, DGD, SNT, qtum)
advantages: as Ethereum series light wallet, mtoken supports all the tokens of Ethereum erc2.0 standard, can control the miner's fee of each coin, can set the collection amount, and has convenient transaction record query, refreshing interface and easy operation, so it is suitable for ICO investors who need to receive a variety of erc2.0 standard tokens and trade infrequently
disadvantages: 1. The "discovery" mole of the wallet is not intuitive enough. 2. The tokens that can only be stored on the Ethereum platform, such as BTC and Neo, can't be stored. At the same time, the bifurcations of bitcoin can't be stored

The platform also has tiaoshao market, which can carry out token trading of physical assets on the chain
advantages: it has high security factor, adopts local private key security mechanism, as well as mobile phone and computer al backup strategy, supports the current mainstream currency, and has a jump market on the platform, which can carry out token trading of physical assets on the chain
disadvantages: usdt transaction must use 0.0001 BTC as transaction handling fee, does not support some small currencies, page optimization is good, but the function is relatively few
