Spain September Harmonized CPI Year-on-Year Preliminary Value

The cryptocurrency market has always been full of drama, especially for investors who have experienced the previous bull run. Looking back, many people still fondly remember the altcoin season; what does this sentiment reflect? During the previous bull run, the prices of cryptocurrencies in the secondary market fluctuated remarkably. Certain altcoins increased in value tenfold within just a week, and even surged a hundred times within a month. Moreover, some, like Luna, achieved nearly a thousand times increase shortly after their listing, while Solana skyrocketed from $2 to $250. At that time, the market atmosphere was exceptionally optimistic. Investors jokingly said, "Money comes like a strong wind," "With an IQ of 50, you can live in a palace," and "Just buy and hold, and you can wait for wealth to come." This almost crazy optimistic sentiment dominated the entire market. At the end of April 2021, many investors entered the encryption field due to news related to Dogecoin. New investors often quickly taste the sweetness, such as Dogecoin yielding 3 times, SHIB yielding 5 times, and even some niche altcoins bringing 10 times returns. At that time, certain small exchanges became popular investment venues. However, the good times did not last long. On May 19, 2021, the market suffered a severe blow, experiencing a sharp correction. In October of the same year, the market formed a double top pattern, marking the end of the bull run. Looking back at this history, we find that the old investors who nostalgically remember the past bull run and the new investors who entered the market last year, reminiscing about the AI frenzy, are essentially no different. What they both miss is that straightforward "simple model" where one-sided rises allowed bold individuals to easily profit. This nostalgic sentiment reflects investors' yearning for quick wealth, but it also reminds us of the market's volatility. In the high-risk, high-reward realm of encryption currency, excessive indulgence in past glories may cloud rational judgment. For investors, maintaining a clear mind and rationally analyzing the current market conditions may be more important than reminiscing about the past madness.

MicroStrategy transformed its investment into Bitcoin during the pandemic, adopting an aggressive strategy with a total investment of $27.7 billion through its own funds and various financing methods, holding 444,262 Bitcoins, thus forming a unique "intelligent leverage" model.

Quantitative arbitrage strategies are popular among investors in the crypto market due to their stable returns and risk control. By hedging the price difference between spot and perpetual futures, investors can enjoy annualized returns of 20%-30% in a bull run and maintain stable returns of 8%-10% in a bear market. Experts emphasize strict risk management and dynamic adjustments, making it suitable for risk-averse investors.

Robinhood plans to develop a blockchain-based platform for tokenization of US stocks, possibly choosing Arbitrum or Solana for technical support.

Enhancing Ethereum transaction confirmation speed: Exploring new solutions The Ethereum network has made significant progress in the past few years, with transaction confirmation times shortened to 5-20 seconds. However, to further optimize the user experience, especially to meet the sub-second latency requirements of certain applications, we need to explore more improvement solutions. Overview of Existing Technology Single Slot Finality The current Gasper consensus mechanism adopted by Ethereum is based on a slot and epoch structure, with one slot every 12 seconds, and 32 slots forming one epoch. Although this mechanism provides strong economic guarantees, it has issues of high complexity and long confirmation times. Single Slot Finality (SSF) aims to simplify this process, similar to Tendermint consensus, where each block can achieve final confirmation before the next block is generated. However, SSF also faces the challenge of increased network load and requires further optimization. Rol
