As for the cryptocurrencies you mentioned, BNB, ETH, RNDR, and ARB are some of the best performing altcoins on the market. For example Binance Coin (BNB) has performed well due to its use within the Binance ecosystem and the growth of the DeFi market. Ethereum (ETH) is the second largest cryptocurrency by market capitalization and has a variety of use cases, including decentralized finance (DeFi), non-fungible tokens (NFT), and smart contracts.

Render Token (RNDR) is a promising altcoin that aims to provide decentralized rendering services for the entertainment industry, while ArbiSmart (ARB) is a platform that offers high yield investment interest, along with trading and arbitrage opportunities.

The crypto market is highly volatile and subject to sudden fluctuations, and thus, it is important to diversify your investments and keep an eye on market trends. if asked to me Matic is a good choice for now.
