Depends on what you want to do with it. For trading I would suggest checking the top 10 coins in
https://coinmarketcap.com/. Look for the ones trading in high volume for the last 24 hrs.
For long investment hold, you can't go wrong with bitcoin and ETH. ICO's use ETH and bitcoin... is bitcoin.

Litecoin is a very good choice. Asians are investing in it. I have buyed some coins. Im waiting now to that litecoin will double his amount. I would then sell all my coins.
After that Im going to invest in btc and then do the same.
