i have, bitcoin,ethereum, litecoin, bitcoin cash,ripple,dashcoin and dogecoin. 
you have a good list of coins and you can hold it for a long time. if you want to do daily trading, then i can suggested to sell half of the each coins and do buy again when the price is down and sell again if the price is high. but i think the last day of this september will be hard day to do trading because bitcoin price is not going somewhere until the end of this month so be careful when you want to trade.
For me i would totally put some trust in waves in ETH. Because i could see that there a lot of altcoins that are being made in there platform. I dont know about others that are not mineable but i would really put some risk unto them.
For me I choose etherium, waves, bitcoincash and deeponion because this alt-coin has a huge opportunity to pump in the future and the development of this alt-coin is still active and we can sure of our investment to be safe.
