1. About digital currency, say some of their own views, you listen to, feel unreasonable just laugh
money, as a measure of transaction value, does not necessarily have value in itself, it can only be used as an intermediate unit of measurement. It's just like China has only RMB as legal tender, that is to say, government guarantee has value. For example, in those war-torn areas, ten jin currency may not buy an egg, which is the reason
back to digital currency, digital currency, until now, no country has recognized it as the currency in circulation of its own country. It seems that last year or the year before last, our country also banned some. In this case, digital currency can only be sold at a price higher than your purchase price, so that you can make money. But digital currency itself does not have any value. Unlike stocks, it is your ownership of listed companies. So if you can't find someone to buy digital currency, it's worthless
the Ponzi scheme in history, the Dutch tulip, when it was the most expensive, a tulip was worth buying a house. When no one bought it, all the tulips rotted. In addition, they couldn't get a potato. Therefore, Buffett said that digital money is a bubble, which is a hoax.
in addition, there is a saying in the stock market that when all the ladies in the vegetable market begin to discuss the stock market, it is the time when the stock market reaches its peak. In my opinion, this also applies to digital currency. When many people are discussing how to make money and how to make a lot of money, the risk has accumulated to a great extent. Most of the time, when the stock begins to fall, many people are still in the previous inertial thinking, thinking that it will rebound soon, and then it will get lower and lower, and they are more reluctant to sell it. This is why many people hold a high position on it
I'm not sure whether it is the highest point of digital currency, but I think that digital currency, which can be issued by anyone, has no purchase value and can only be sold to others. I think it's a fraud.

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
