Two alternative cryptocurrencies within the top 100 rankings have defied the downward trend in the crypto market and experienced significant gains this week, thanks to new developments. Helium (HNT), a decentralized Internet of Things (IoT) network, announced that two major US carriers have initiated tests to offload their traffic onto the Helium MOBILE Network. MOBILE, a decentralized wireless provider based on the Solana blockchain (SOL), is part of the Helium ecosystem, which aims to facilitate communication and data sharing among IoT devices by supporting smart contracts and enterprise applications. At the time of writing, HNT is trading at $6.67, marking an increase of over 18% in the past 24 hours and nearly 48% in the past seven days, making it the 66th-ranked cryptocurrency by market cap. On the other hand, Sui (SUI), a smart contract platform, experienced gains after Grayscale, a prominent crypto company, announced the launch of a trust specifically designed for SUI. Currently, SUI is trading at $0.86, with a 2.55% increase in the past 24 hours and nearly 55% increase in the past seven days, placing it as the 35th-ranked cryptocurrency by market cap. In contrast, the overall crypto market cap has decreased by 1.18% in the past 24 hours and more than 13% in the past two weeks, according to CoinGecko.
