The past and present of bitcoin
In fact, the recent wncry virus is not the first time that blackmail software has become powerful. Not long ago, Android system also appeared a blackmail software, mobile phone encryption after ransom. After the software was checked and killed, it soon made a comeback with an upgraded version. This new version of blackmail software infects files with a random key, and even attackers don't know how to unlock it. Even users pay ransom in vain
we can see that with the continuous development of IT technology, although there are many IT employees, the main employees are mainly concentrated in the fields of mobile platform, cloud and artificial intelligence, and the most popular programming language has graally evolved from C and C + + for underlying operation to managed Java or even go language for modeling. The field of information security is a technology that directly faces the bottom. Fewer and fewer people are engaged in the bottom programming, which means that the number of practitioners of information security is getting smaller and smaller. The direct consequence of this phenomenon is that the backward technology can attack the advanced technology in the network world, which is very similar to the invasion of advanced civilization by the backward barbarians in human society. The recent outbreak of wncry virus may come from North Korea, which also confirms this trend from the side. Some organizations and even countries are not qualified to engage in high-end technology, but the virus they write can spread all over the world. Blackmailer software has further expanded the scope of attack, such as online games, smart cars and wearable devices have a large number of leaks. Reviewing the history of such software can be roughly divided into the following stages
from the current situation, there is no sign of easing the bifurcations of bitcoin, but the emergence of bitcoin ETF and wncry virus has pushed the price of bitcoin to new highs. Personally, I think the short-term rate of bitcoin will probably exceed 20000 RMB. However, considering that there is not all the competition for bifurcations among varieties such as lightcoin, from the perspective of investment, if bitcoin falls again e to the competition for bifurcations, it is actually good for lightcoin. Therefore, if some readers hold a lot of bitcoin and do not want to sell it, You can consider hedging with long Leyte
from the perspective of information security, the bifurcation problem is likely to affect bitcoin's status as a ransom for blackmail virus. The author thinks that the virus accepting Wright coin and ether coin as ransom will be born soon
however, blockchain currencies are more or less troubled by processing speed, and the encryption algorithm is not easy to upgrade. In the long run, the risk is relatively high, and the signs of short-term price manipulation are relatively obvious. If the psychological enrance is not strong, just watch their running track
Since the second half of 2020, the price of bitcoin has been going up all the way. Up to now, bitcoin has broken through the $50000 mark, which can be said to be a straight-line surge. Why are many short sellers not optimistic about their prospects before, but their prices are running all the way to the top? Is it that they say no, but in fact they are very honest< in fact, the price surge of bitcoin is e to the fact that musk, the founder of Tesla, the new world's richest man, has publicly expressed his support for bitcoin, and that multinational financial consortia such as JPMorgan Chase and MasterCard have also provided bitcoin platforms, which has led to a sharp rise in the price today, Xiaobian will give you some ideas about bitcoin
First, the past and present of bitcoin< p> Bitcoin is a kind of virtual P2P currency proposed by Nakamoto Cong on November 1, 2008. Its biggest feature is decentralized, peer-to-peer transmission service, which does not need to be issued by the National Central Bank and other currency issuing institutions. Moreover, it is obtained by cracking the encryption algorithm, so its security is very high, and the total number is limited. Now, it is more and more difficult to obtain bitcoin, which also gives rise to & lt; Mining machinery& ldquo; Mining & quot; And other instries. Due to its limited total quantity, this virtual currency is very scarce and can be used as an investment proct
the price of bitcoin has been at the highest level in history after a period of rapid rise. It is not known whether it will continue to rise or let it go all the way. For us ordinary people, this price is already sky high. We'd better wait for the fight of major capitals. Netizens, what's your opinion? Welcome to comment area message exchange

we can see that the four precepts of Lafan and the treasure money of Yuli teach us how to improve our destiny, but even if you immediately pursue the good, do nothing about the evil, support the three treasures, and inherit the Dharma, you can not change your destiny all at once and quickly. You can also be cared by the gods, Buddhas, and Bodhisattvas. Graally, you can lighten the karma, eliminate the karma, protect the future, and honor future generations
the so-called crime, karmic handicap and mistake are just like the reality. If you are in trouble, immediately admit your mistake, actively apologize to others and save your mistake, then you will be relieved in law, just as money is deposited in the bank with interest. If you run away, escape, be stubborn and tough, the punishment will not be light in the future, and retribution will be like this. So when you start to amend the law in the first year, you will suffer a lot. Buddhas, Bodhisattvas and immortals will take out your past karma and sins in advance, and let you suffer and repay lightly. Don't be afraid, persistence makes light.
in the three collections of Pali and the middle part of the Sutra of the fool and the wise in Theravada Buddhism, the Buddha gives an example to describe how long a fool who falls into the evil way must suffer in the evil way. He asked the monks, "suppose someone throws a yoke with a hole into the ocean, and the east wind blows it to the west, the west wind blows it to the East, the north wind blows it to the south, and the south wind blows it to the north. Suppose a blind turtle rises to Shanghai once at the end of every century. What do you think, monks? Can the blind turtle put its head through the hole in the yoke? "
"Buddha, after a long time, it may be able to do this."
"bhikkhu, I said that the time it took for the blind turtle to put its head through the hole in the yoke was shorter than the time it took for a fool to be born into the world after falling into the evil way. Why? Because in the evil way, there is no way to repair, no good to repair, no good to create, no good to create. In the evil way, killing each other and the law of the jungle prevail. "
therefore, it is almost impossible to repeat the previous story, but the samsara of life and death is always repeating.
