i think you should keep it,it is best and it have very fast transaction and it have good geolocation technology so it price will increase very soon but you should hold it.

bitcoin and etherum now deserve to be one of the coin purchases but in addition to these two coins you can buy neo coins or eos as one alternative option to get profit when the price is high.

For now no one can predict a potential altcoins because a lot of them are shitty and not more usefull and some of them may good at start and disappear at the end of ico so you cannot find a best altcoins now at a glance.
