My opinion is Ethereum, it is quite stable, has good potential and is suitable for long-term investments.

These are ETH, Ripple, Waves. You can also check Neo and EOS. Their characteristics such as security and volumes are really high and promising.

I think for now the good thing for you to buy is Ethereum, NEO and LITECOIN. Almost all coin now is very good for you to buy because all coin in my opinion are at low price condition to be bought. Therefore, with conditions like this will definitely benefit a time when you resell.
