for 2-5 year old portfolio i would only consider bitcoin and nothing else for that long. even if it was 100% bitcoin.
for a long term which is at least 6 months to 1 year i would consider litecoin because of the SegWit and afterwards the implementation of Lightning Network and all the other features that will come with SegWit. price will be in a bull market for months to come.
i would be very careful with my investment in ETH, that is not an stable currency. specially with all the hard forks it has every now and then.
DSH seems to be in a bubble right now. i fear it may go back down to 3 digits (500 satoshi) price soon but i may be wrong!
i agree with PIVX, NEM, LSK, AUG choices.
add wings and POSW coin too, these are hot these days. also ARK is not a bad thing to keep in mind.
Statis is also being pumped these days
