币界网报道：Arbitrum [ARB] surprised the market with a clean 5% gain, standing out as other major altcoins struggled to find direction. The reason? Robinhood’s announcement. Why is ARB surging? AMBCrypto previously reported that Robinhood will use Arbitrum’s Layer 2 to launch tokenized stocks, ETFs, and shares for EU users, with plans to build a custom Orbit-based chain in the future. Naturally, the market interpreted this as a huge endorsement of the ecosystem — a positive for ARB. At press time, Arbitrum is trading around $0.342, up 4.88% in the past 24 hours, according to CoinMarketCap. While it leads the daily altcoin gains, trading volume is down by nearly 30%, suggesting low participation behind the move. Experts’ Predictions Despite low participation from crypto investors, experts and analysts are showing strong interest in the coin and appear to be making bold predictions. One expert stressed that ARB is unlikely to drop below the current levels again, highlighting the asset’s strong upside potential. Meanwhile, another expert made a bold prediction, stating that these are not the only posts that have appeared on X; there are several other optimistic posts that show the experts’ strong interest in the coin and its upside potential. Price Action and Key Technical Analysis According to AMBCrypto’s technical analysis, the ARB token has been fluctuating within a descending channel pattern between the upper and lower boundaries since May 2025. With the recent price increase, the altcoin appears to be heading towards the upper boundary of the channel. If this rise is sustained, ARB could rise by another 7% to retest the top of the channel, close to $0.37. Moreover, if the momentum continues and ARB breaks out of the channel, there is a high chance that the altcoin could see a price increase of up to 34% in the near future. At press time, ARB is trading above the 50-day exponential moving average (EMA) on the daily chart, suggesting a possible shift in trend and that bullish momentum is building in the short term. $2.20M of ARB Leaves Exchanges CoinGlass’s accumulation data supports this structure. In the past 48 hours, ARB has seen $2.20M of exchange outflows, including a daily net outflow of $2.57M on July 1. Such shifts typically signal investor confidence — whales moving tokens from exchanges to cold storage or long-term holdings.
