Here you are asking good question but here you are small limited to your questions , here you need to ask best choice of coins for long and short term , well here I would like to suggest for the short term coin are etn , dgb , BCN  coin and for the other altcoins which are better to hold for long-term  are bitcoin , etherium , dash , litecoin , ripple , etherium classic  , XRP etc
And also beside of these coin we can choose another for average 1-2 month hold coins which are uae coin , Pak coin ( that fluctuate below 100 Satoshi and then it get up to 300 Satoshi easily ) ,
But here my suggestion is also for you is that don't invest in anything until you make yourself better analysis that you did good from.your point of view .
