Polkadot's DOT experienced a sharp decline following a major exploit on the Hyperbridge platform, where a hacker minted 1 billion bridged DOT tokens, netting approximately $237,000. The incident led to a temporary suspension of transactions on exchanges like Upbit and Bithumb. Despite initial panic, the market rebounded with a 17% recovery after developers clarified that the main Polkadot chain remained secure.The exploit, which resulted in total losses of around $2.5 million, initially shook confidence in bridged assets. However, sentiment quickly improved as users realized the breach was limited to bridged tokens. This reassurance led to increased network activity, with transaction counts rising and daily active users growing. DOT's price surged from $1.146 to $1.354, although it now faces resistance near $1.35.Traders are closely monitoring DOT's price action, with a potential breakout above $1.35 signaling continued bullish momentum towards $1.50. Conversely, a rejection could see prices retreat to $1.20 support, leaving the market in a critical zone of uncertainty.
