Legal currency cannot be replaced arbitrarily.

Expect bitcoin to be number one.

Buffett thinks "Bitcoin is a real bubble because you can't value Bitcoin. Bitcoin is not an asset that can produce value."

If I have extra money, I will buy bitcoin, but I will not buy it in this way.

"What bitcoin is playing with is the heartbeat," soaring and plummeting, who can say the risk is small?

I agree with you that the unpredictable and risky nature of Bitcoin is a big problem. Having a stable income has a sense of security.

At present, the global bitcoin transaction volume has reached more than 200,000 daily, and the number of merchants accepting bitcoin payment has reached several hundred thousand and is growing rapidly. In some developed countries, using only Bitcoin already meets day-to-day needs. It is believed that in the near future, Bitcoin will become the mainstream currency on the Internet. But it will not become a legal currency.

Some people predict that the future cryptocurrency will replace about 25% of the national currency.

Bitcoin will survive in the next 10 years. Bitcoin has been developing for more than ten years and will not easily fail.

The number of bitcoin is too small to be widely circulated in society. And it exists not as a guarantee of national credit, but as a basis for trust among bitcoin players, so the credit of this "currency" is relatively low.
Moreover, the small number of bitcoins, and their concentration in the hands of a few large players, makes their price highly volatile. That's basically not money. Because an important prerequisite for a common currency is price stability, otherwise the economic order will collapse.

The Ponzi scheme is a fraudulent investment scam that promises low risk and high returns. The Ponzi scheme rewards old investors by acquiring new investors. But on the contrary, bitcoin, in fact, many people who have had Bitcoin very early in fact did not receive excessive returns on investment. I know that many people have bought thousands of bitcoins to spend on pizza, mining equipment, and gambling. Sites, video games.

If bitcoin succeeds, those who don't buy it because they hate it will surely regret it.

采矿机的收益曲线不断下降，当收益曲线达到与电价相同的水平时，就达到停产点。

Other currencies are derived from Bitcoin. The current value of Bitcoin cannot be surpassed by other currencies.

Never put eggs in one basket.

Whether or not money has intrinsic value should depend on whether it can be an exchange medium and facilitate transactions, and maintain a certain degree of scarcity.

Bitcoin is both a belief and a money. We believe in bitcoin because we believe it can bring us wealth.

The higher the value of Bitcoin, the greater the controversy.

The value of Bitcoin is growing.

Where there is a bubble, there is a huge gain.
