According to Mihir (@RhythmicAnalyst), there has been a noticeable pump in the prices of Proof of Work (PoW) coins, specifically mentioning Litecoin (LTC), Bitcoin Cash (BCH), Bitcoin SV (BSV), and Dogecoin (DOGE). This surge indicates a growing interest or speculative trading activity in these cryptocurrencies, potentially due to their PoW mechanism which is often highlighted for its security and decentralization aspects.
