币界网报道：Ethereum mining service provider NiceHash has launched a promotional campaign offering users 15% free hash power when purchasing mining contracts. The limited-time offer applies to all Ethereum mining contracts purchased on the platform, effectively increasing users' mining capabilities at no additional cost. According to NiceHash representatives, this initiative aims to help miners maximize profits during Ethereum's current price volatility while maintaining operational efficiency. The platform utilizes a unique marketplace model where miners can buy and sell hash power, creating a flexible ecosystem for cryptocurrency mining. Industry analysts note that such promotions could attract more small-scale miners to participate in Ethereum mining before the network's anticipated transition to proof-of-stake. NiceHash has emphasized that the free hash power will be automatically applied to users' accounts upon contract purchase, requiring no additional steps from customers. The promotion comes as Ethereum mining profitability faces pressure from increasing network difficulty and fluctuating ETH prices. NiceHash, founded in 2014, has grown to become one of the largest hash power marketplaces, supporting multiple mining algorithms and cryptocurrencies. The company recently expanded its services to include automated profit-switching features that optimize miners' earnings across different cryptocurrencies. Market observers suggest this promotion may be part of NiceHash's strategy to maintain market share amid growing competition in cloud mining services. The offer is valid for a limited period, though the company hasn't specified an exact end date for the promotion.
