Too many options to list.  If you're looking to expand your portfolio (not dump all your money into one)  I would suggest DigiPulse.  They are providing a peer-to-peer, anonymous, and decentralized solution to digital asset inheritance.  Currently in open beta so you're free to go through the entire process to give you an idea of how the final product will work.  Currently in progress of an airdrop to raise awareness and platform launch slated for July.  May and June should be good months for DGPT running up towards the launch of the product.
