币界网报道：MiningToken, a cloud mining platform, is promoting daily returns of 3.0% to 4.0% for investors through its Litecoin and Dogecoin cloud mining rigs, while emphasizing eco-friendly operations. The platform claims to use renewable energy sources to power its mining activities, addressing growing environmental concerns in the crypto mining sector. MiningToken offers various investment tiers, with contracts starting from $250 for Litecoin and Dogecoin mining, promising fixed daily payouts. The company highlights its user-friendly dashboard, instant withdrawals, and 24/7 customer support as key features. However, potential investors are advised to exercise caution, as high daily ROI promises in cloud mining have historically been associated with risks, including Ponzi schemes. The platform's long-term sustainability remains unproven amid fluctuating cryptocurrency markets and regulatory scrutiny.
