If investing i am thinking:Neo,OMG,Lisk
Good picks, especially for a short 2-3 month period. However, i'd swap out Lisk for something else. Probably Ethereum. Don't worry about BTC pumping. It's already pumped $1000 in a span of 2 days. Anything more would be slightly unlikely.
I second to that. I am not always comfortable with altcoins that gets hugely pumped in the market and then crash back so bad later on without at least maintaining some good support level. For trading though, it is not bad and to hold some coins like this, I would rather just trade them first and make use of the profit to buy back later on at dips.
However, the other ones are good picks and I am sure the Alt market is really going to grow bigger than it is right now later on in coming years.
