You have to think of integrating Lisk (LSK), probably one of the best crypto for near futur and cardano (ADA) for long term.

Code is life and so if you have ETH you have to have Ethereum Classic (ETC) as specialy that charles H will integrated easely with Bitshares and Caradano.

Funny to see that you do not have BTC or BCH.

Otherwise good choice of coins, you could probably argue on the percentages.
