Ether continues to trade above $1,500, up around 0.7% over the past day. Binance's BNB was relatively flat as it flirted with $300; Ripple's XRP rose 0.9%, and Cardano's ADA gained 1.1%. 

Shiba Inu tacked on 2.8% following the announcement that developers are preparing to release the meme token's Layer 2 network, called Shibarium, in beta form. Transactions on the Ethereum-based chain will be paid for using bone, the governance token of the Shiba DAO.

Bone tokens will be used to reward validators and delegators on the network, and 20 million currently worth $27 million have been reserved for the payments. Developers say the system will improve the utility of the bone token, which jumped over 12% to $1.34 following the announcement.
