There are various coins that are good investment. It only needs proper research and findings before one could conclude which will moon.
Generally, eth and BTC are favourites and still remain so.  However some altcoins are still good.

Of recent, trust wallet token got listed and got a few gains with good volume. I bought some and waiting for dip to buy more again. Same with ZIL too.

Personally, I don't like xrp so I don't really buy it. I'll prefer Binance coin - BNB as it gained over the past weekend. Most altcoins are in green as a result of bitcoins moving up. So your research band stick with what works.
