After studying steem & ripple in depth, next target alt-coin for me is COVAL. It seems to be a solution which bridges the blockchain based solutions to the real world existing internet based business solutions. It may turn out to be the very useful if there is any particular service provider which can transfer the existing systems of well established business model & value offerings which do not really need to get disrupted but need to add blockchain as an added benefit to the current product.
first principle wise blockchain is just another ledgering technique which can help every business as the internet technology did for every possible business.
