- The article is poorly written and lacks coherence. It jumps from one topic to another without providing a clear structure or logic. For example, it starts with the price increase of Arbitrum, then mentions its all-time high, then compares the volatility, and then talks about the trading volume and supply. This makes it hard for the reader to follow the main point and grasp the key information.
