Store Ethereum with trezor
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 chipuses 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 fastthe 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 youenj's total supply of tokens is 10000000000 enj (1 billion), which is an alternative erc-20 token on the Ethereum blockchain. It also supports alternative and irreplaceable erc-1155 smart contracts. The current price is: ￥ 0.3429 (2020-03-17)
the Enjin coin ICO was held from July 2017 to November 2017 and raised about $22 million in eth. About 80% of the total token was sold, and the remaining 20% was allocated to the founding team, companies and investors. Combined with other sales channels, the project raised about $35 million
enj cannot be g like bitcoin. When users create custom erc-1155 assets, enj will be destroyed
enj (2020-03-17) worth about 60 million RMB is traded every day. The cryptocurrency exchanges that accept enj include ratoken, coin security, upbit, bittrex and hitbtc. Trading pairs including BTC, ETH, usdt and fiat currencies, such as KRW and USD, are accepted in Korea and the United States
as erc-20 token, enj can be stored in any erc20 compatible Ethereum wallet, including myetherwallet, trust wallet, trezor and Archos hardware wallet. The team also developed Enjin smart wallet, which makes it easy to purchase digital goods with encryption. Following the release of the ecological win-win plan by okcoin and coin security, fire coin also launched the "fire coin cloud" output technology, and the exchange's "ecological war" started
on July 20, fire coin, a digital asset trading platform, announced that fire coin Group & quot; Fire coin cloud & quot; The business was officially launched, allowing users to build a digital asset exchange on the existing platform of fire coin. According to the introction of fire coin, at present, more than ten large international institutions including dbank group, Taiwan Gifu group, Russian state veb bank and Asia Pacific International Holding Group have become the initial partners of fire coin cloud. Fire coin cloud provides four major solutions: OTC, currency exchange, operation and ecology

this new proct is designed to establish OTC and digital asset trading, and help partners complete order integration and wallet system deployment. In addition, the fire coin cloud platform will also provide asset management and clearing services. Li Lin, CEO of fire coin, said that blockchain is a very attractive instry. Fire coin hopes to share with global partners the experience, ability and resources accumulated by fire coin in the field of digital asset exchange and even the whole blockchain ecology, and work together to promote the development of blockchain instry and achieve win-win results
previously, okex launched the "open and win-win plan of digital asset exchange", and coin an also released the "Alliance Plan of digital asset exchange", which are similar to fire coin cloud. They all use their own experience, ability and resources to help partners build a digital asset trading platform and seek ecological win-win.

Matlab neural network toolbox can be used to extract samples first, normalize them with mapminmax function, then establish the network with newff function, set training parameters, train them with train function, and finally see the prediction results with SIM function
in the process of training, there is a performance that can be observed, and its training goal is the goal you set. In the process of training, it will automatically separate a part of the samples as validation verification, which can ensure the fitting. In order to evaluate the effect, the accuracy of the final prediction should be considered
The appendix is an example of BP predictiontrezor.
To remind you, it is not safe to store cryptocurrency in the trading website
summary
we must be careful when managing the storage of cryptocurrency, never put your "position" directly on the trading platform, and you must take good care of your private key. If possible, the cold storage of cryptocurrency can be realized through hardware wallet or paper wallet. In addition, be careful of phishing attacks or Internet fraud. Please be careful of every hyperlink and URL you encounter in the process of surfing the Internet
