Polkadot (DOT) has experienced another downturn in the current trading session, failing to surpass the critical resistance level of $4.50. On Friday, DOT reached an intraday high of $4.49 but was unable to maintain its upward momentum. This marks a continued struggle for the cryptocurrency to break through this significant price barrier. Market analysts suggest that sustained resistance at this level could indicate a period of consolidation or potential further declines. Investors are advised to monitor the situation closely as the market dynamics evolve.
