1. In fact, the rise and fall of digital currency is a normal situation. The key is to see whether you are optimistic about its long-term value. Relatively speaking, if the long-term value is worth investing in, then the short-term decline can be ignored. At the same time, if you don't know much about digital currency users, it is recommended to choose a reliable and good platform for investment. The investment period needs more than six years, Word of mouth should always be good, you can take a look at AEX, fire coin these two, but also more reliable, you can also understand their own network first

2. 1. Work is done by multiplying the force by the distance in the direction of the force. There is no displacement in the direction of gravity. So gravity doesn't do work. Just imagine, if there is no resistance, doing a little work can make the car move far away, which has nothing to do with the weight. The inertial thinking in life is that the heavier things are, the more work they need to do. In fact, the weight of 900N has become rolling resistance in disguise. Without weight, of course, there will be no resistance
2. Law of conservation of energy: 0.5mv end ^ 2 = MGH + 0.5mv beginning ^ 2

Recently, the attention of the emerging cryptocurrency, dogcoin, has been on the high side. In this round of sharp decline caused by the cryptocurrency "big market" bitcoin, dogcoin has been falling all the way; It fell to as low as $0.4 a piece and was almost cut off. As for the reasons for the sharp drop of the currency circle, the foreign exchange survey has some opinions:

1, the demand for the currency circle has decreased

under the trend of epidemic spreading, there are fewer transactions around the world, people become more conservative, and the total amount of social consumption is greatly reced. At this time, the transactions settled with bitcoin are greatly reced, the demand is reced, and the price will fall

The risk of price collapse is high

affected by capital speculation, the price of virtual currency has gone up and down, which makes it difficult for ordinary investors to predict and easily lead to position explosion and loss. In history, cryptocurrencies such as bitcoin have suddenly dropped at the peak for more than ten times. Recently, behind the dog coin's crazy rise and then plummeting, is a "leek cutting game" in which the capital tycoons represented by "Musk" reap ordinary investors

3. Virtual currency has no intrinsic value and the risk is very high

virtual currency does not have the function of currency transaction in essence, and it is not recognized by any country in the world. At present, the price of cryptocurrency is rising sharply, mainly e to speculation caused by market speculation. Once countries in the world explicitly deny the value of these virtual currencies that are not controlled by the state, the virtual currency will instantly become worthless, And the virtual currency held by the majority of investors will be completely locked up

although dog coin is now the fourth largest cryptocurrency with a market value of 68 billion US dollars; Second only to bitcoin, Ethereum and coin. It may be the "asset" with the biggest increase in recent years. However, the reason why people can not establish their faith is that the market has not yet reached a certain consensus, and they do not understand what role the dog coin will play in the future. From the perspective of investment, for such cryptocurrencies, which are not practical and mainly rely on financial attributes to tell stories, it is quite worrying to tell the truth

in terms of investment, cryptocurrency is very promising, but please be cautious no blind obedience and no faith in dog money; Dog coin, as musk put it, "is just a fun collection" or "joke."
