1. The title of the article is misleading and sensationalized. It implies that Polkadot is a rising star in the cryptocurrency market when in fact it has been struggling to maintain its value and face resistance from other competitors. A more accurate title would be "Polkadot Continues To Lose Ground In The Cryptocurrency Race".
2. The article does not provide any context or background information about Polkadot, such as its purpose, features, benefits, or challenges. It assumes that the reader already knows what Polkadot is and how it works, which may confuse or alienate newcomers to the cryptocurrency space. A better introduction would be something like "Polkadot is a decentralized network that enables scalable, secure, and interoperable transactions between different blockchains. It aims to solve the problem of interoperability in the fragmented crypto market by allowing different chains to communicate and exchange value."
3. The article focuses too much on the short-term price fluctuations of Polkadot, which are not indicative of its long-term potential or performance. It fails to mention any significant developments, partnerships, or achievements that Polkadot has made in the past year, such as the launch of parachains, the integration with Acala Network, or the collaboration with Chainlink. These are important milestones that showcase Polkadot's innovation and progress in the blockchain ecosystem.
4. The article uses negative language and tone to describe Polkadot's situation, such as "contrary to its negative trend", "experienced a 4.0% loss", or "face resistance from other competitors". This creates a pessimistic and unfavorable impression of Polkadot in the reader's mind, without providing any constructive criticism or suggestions for improvement. A more balanced and objective approach would be to acknowledge both the strengths and weaknesses of Polkadot, as well as its potential opportunities and threats in the market.
5. The article ends with a chart that compares the price movement and volatility of Polkadot, but does not explain what it means or how to interpret it. It assumes that the reader already knows how to read and analyze charts, which may intimidate or confuse those who are new to trading or investing in cryptocurrencies. A better conclusion would be something like "The chart above shows that Polkadot's price has been volatile and unpredictable over the past year, but it also has a lot of room for growth and development if it can overcome its challenges and deliver on its promises."

Overall, I think
