I would say to pick up some of the obvious choices ... ETH, WAVES, OMG, NEO.
You could also get crazy and pick up some of the up and coming projects tokens (higher risk of course) -- MUSIC, FLO and FUN (just had a large burn).
I bought before OMG and NEO. I didn't buy a lot because I really think we are in a bear market for alts right now. I think they will fall even more when the next fork comes. As long as BTC is unstable alts are dropping, regardless if BTC shoots up or down. I am happy with the amount of my altcoins right now, if they dip a lot I will add some positions there. My gem which salvages all my losses is smartcash. I am up x8 in this one.
That's a good move, we published an article about smarcash some days ago.
The performance of smartcash has been considerable in the past week, +114,34%, and +312,92% in the past month, but according to the Robot, its probability of upside in the short term remains elevated and equal to 56,18% (this is the link to our full article:
