I believe there are four major categories of blockchain platforms these days:

1. Store of value (Bitcoin, Litecoin)
2. Smart Contracts (Ethereum, Lisk),
3. Privacy (Zcash, Monero)
4. Governance (Tezos, Decred)

Does anyone think there are other value categories for Blockchains?  Not investment advice, but I think it's prudent to plan for the eventual success of each of these categories...
