A number of smaller cryptocurrencies are seeing major double-digit gains today, as 80% of the top 100 projects have seen positive returns in the last 24 hours.

Top performers in the top 100 projects include the ethereum based decentralized app marketplace Centrality (CENNZ). The project has risen a mammoth 47% today, following the news that its first major announcement is coming up in four days' time. Second place for one-day gains goes to Siacoin (SC)—the decentralized storage platform is up 25% on the news that the token will now be listed on the Kraken exchange, and that its network has grown over 20%, to hit an all-time-high network storage capacity of 600TB of data.

Two more projects that also saw major gains today were 0x (ZRX) and Chainlink (LINK), both up around 18% on the day. Chainlink has carried on its momentum from yesterday's 12% rally while the decentralized exchange protocol 0x has been boosted by the news of its upcoming integration into prediction market Augur's new platform.

Despite the major altcoin breakouts, the number one cryptocurrency Bitcoin is flat on the day. According to data from Coinpaprika, the total crypto market cap is up a modest 1% to $227 billion with Bitcoin dominance at 65%—or nearly two-thirds of the whole pie.

Bitcoin dominance is now down from its 70% high of early September, but the market may be waiting for some larger-cap altcoins to break out before any possible alt-season can be confirmed just yet.
