As a blockbuster year for cryptocurrencies ticks to a close, some of the smallest coins are having a moment.
Polkadot and Cardano were among coins posting the biggest moves on Monday following a relatively quiet holiday weekend, with each up more than 6% at one point, before giving back some gains, according to data from Coinmarketcap.com. Bitcoin, the largest digital asset, was little changed at about $51,000 as of 5 p.m. in New York, as was Ether at about $4,060.
