Security of bitcoin all node Wallet

1. bitcoin technology, including protocols and cryptography, has a strong security record, and bitcoin network is perhaps the largest distributed computing project in the world. The most common weakness of bitcoin is user error. The bitcoin wallet file that stores the private key may be accidentally deleted, lost or stolen. This is very similar to physical cash stored electronically. Fortunately, users can use reliable security policies to protect their funds, and they can also use providers who provide good security levels and theft or loss insurance services

in fact, safety is not safe but has the final say in practice.

2. Now there are potential solutions. More nodes help make bitcoin network faster, healthier and more resistant to censorship. Decentralization is one of the core principles of blockchain based cryptocurrency. Fortunately, there are more potential solutions to solve this problem, which can make it easier for users to run a full node

first of all, the cost of hard disk has dropped from the lowest of US $0.025/gb in 2017 to US $0.15/gb, a 40% drop in three years. If this rate of decline continues, then by 2022, the decline rate of hard disk home will be faster than the growth rate of bitcoin, because over time, hosting a full node will be more economical
however, there are some technical solutions to solve this problem, which can rece the storage burden of the whole node. One of the most common solutions is light node. These nodes use a simplified payment verification method to verify transactions. Users only need to download a small part of the blockchain, but they need to rely on the third-party full node hosting the whole blockchain.

8. Bitcoin's wallet platform has never been used or heard of. It is estimated that it is a mobile phone investment app. There are many such investment apps now, and the quality of each platform is different. Many platforms, in order to attract investors, often use a lot of advertising, improve the yield, give gifts and other means to expand the popularity and increase the attention of investors, but their own strength is unknown to outsiders, If you want to know whether a platform is reliable or not, first of all, it depends on whether the investment target is standardized, whether the investment interest rate is too much higher than other platforms, whether the certificates of financing enterprises are complete, and whether other investors prefer not to invest when their evaluation of this platform is unclear. If you want to invest, you can't just look at the interest rate, and you need to be cautious when there are risks
