Curate portfolios of pools and use them to spread stake across multiple stake pools. This functionality will soon be available on Cardano.
It is important to note that multi-delegation of stakes is yet to be released on Cardano however this site is up and running, in BETA, to allow the community to prepare to further the decentralization of the Cardano network through the utilization of this functionality.
On Adafolio there are both portfolios of pools curated by the founder of the site and community curated portfolios of pools. Anyone can go on and curate their own novel portfolio of pools.
Adafolio presents cards of the portfolios displaying the average return on stake percentage, ROS%, as well as how many pools are in that specific portfolio.
