Polkadot (DOT) experienced a 3% decline, dropping to $1.83 and breaking the $1.90 support level amid a broader cryptocurrency market downturn. Despite recent integration with Coinbase, DOT faced increased selling pressure, with trading volume surging 340% to 9.47 million tokens. A bearish trend is emerging, with $1.90 now acting as resistance and the next support target between $1.75 and $1.80.
