Waves have a solid team and a growing community..i think at the moment it's still a good investment for short-medium term.
As other users have already told you..you should do your own research before investing your money in any coin or token.
If you are new to crypto i suggest you to start with a cheaper coin ruled by a good team and community.
For example DeepOnion : very solid project, strong community and brilliant future. The price x unit it's still under $1.00, a very good entry point at the moment
