bitcoin investment is inherently risky. It's like gambling. There are losers and winners. When it goes up, it's a sudden wealth. When it goes down, it's a poison that will kill you. To put it bluntly, in terms of real bitcoin investment, the real money makers are the big guys. At the peak of bitcoin's boom, the big guys had fierce eyes, cashed in in time and made a lot of money. At that time, those without cash out were cold. This kind of gambling like way, you can't blame others for your loss. There are risks in investment, so we should be cautious when entering the market{ RRR} anyway, I dare not touch this thing, our IQ is limited. We can't play with this stuff. I'm afraid I'll have a party on the rooftop. Be careful
2. "Indivial fixed effect model is a model with different intercept for different indivials. If the intercept of different time series (indivials) is different, but for different cross sections, the intercept of the model has no significant change, then the indivial fixed effect model should be established
in fact, we should look at this intercept in combination with the economic problems you study. The most common example is the relationship between consumption and income. Many books use this example. If the income is 0, the intercept term is spontaneous consumption. In this way, the spontaneous consumption is different in different regions, and the intercept term is different. You can sort the spontaneous consumption
however, for many panel models used in practice, this intercept term is usually not explained. Because the data processing is different, the economic significance of the conclusion is different. If you use natural logarithm for all data, after you express the mathematical model, you will know what the intercept term is
therefore, in the final analysis, your economic model is the most important.

3. Bitcontinent is a mining machine manufacturer
the mine is a place where they also use machines to dig coins, where electricity is cheap

4. I don't think so. At the peak of bitcoin, it's very expensive and global. Although the current idle fish coin can be exchanged for items and red envelope coupons, the value of idle fish coin is very low, and it is only used by idle fish users.
