I think this is a good list. Zcash and Monero are good privacy plays. Though, Ethereum and Zcash have been collaborating for a time and have said they are looking to implement zero-knowledge cryptography on Ethereum transactions.

I might add OmiseGO (OMG) to the list. They recently acquired a payment processor in Asia(think Paypal for Asia) and have an existing business model. Their goal is to expand their base and improve the speed of transactions. It is still the early days for these guys...but I think they will be a future star.
