The digital currency wallet is the hardware wallet, which means that the private key of digital assets is stored in a single chip, isolated from the Internet, plug and play. Hardware wallet can't guarantee 100% security. For example, if a geek gets your hardware wallet and doesn't know your private key, it may be cracked by violence. It's just one of the safest storage methods compared to other storage methods
many block chain entrepreneurs at home and abroad are optimistic about the development of this field, so they begin to build more hardware wallets. In the case of the exchange being stolen a lot of money and the software wallet being stolen from time to time, many investors regard the hardware wallet as the last moat

American Stock Research Society points out: different styles of strategies have different requirements for back testing, such as multi factor stock selection or trend strategy. The following points should be noted:
1. Distinguish the data in the sample from the data out of the sample, which is very similar to machine learning. The data in the sample is used for training, and the data out of the sample is used for verification the purpose of this is to avoid the over fitting trap
2. Income distribution: look at the income distribution of all transactions after your back test, and see whether your income source is a few times of large income or a few times of small income if it comes from a large return, your return will fluctuate greatly, and the firm offer will often fail to achieve your effect
3 if you have a parameter that is too sensitive to adjust, it will have a great impact on the revenue, and the situation of your real offer and the simulated offer are also likely to be different
strictly speaking, this kind of strategy avoids some common pitfalls, and it is relatively easy to achieve back testing and real offer
