For long term use, try to buy bitcoin and ethereum, i believe this 2 currency will perform better and has the long term goal unlike other altcoins and coins out there, who are good at first only, if you wanted to trades or short term use, better investment altcoins which are new or just recently done their ICO, in that way, you can gain profits when it will pump and dump.

Me too, i am a long term holders of both this currency, although i loss a lot because i bought it when the price of BTC hits 13k usd., but its okay, i do not care about market prices, i care about the future year to come.

Have a great day ahead.
