I do not recommend staking on anything that has not a long lasting record of real use for the network, since staking is just about getting rewarded for the safety of a network and that only makes sense if the network has sufficient transactions to  make it even worth being secured. Many people are confused with words such as "dividends" or "returns" but the truth is that value cannot be generated without user willing to use the underlying network. How many use cases are already in place for the network of your choice? Probably none.
