In my opinion, you should first learn the bare technical details as to how to run your own wallet. (For example, for Bitcoin, a good desktop wallet is
Electrum) Then you should consider investing.
Don't rely on somebody else to keep your coins' private keys. I've never used Exodus, so I don't know, they could be a reliable company and a good solution. But, someone else is holding your private keys for you, and IMO, that's a huge no-no.
So, learn how to be responsible of your private keys first. Then, go to a proper exchange and buy the coins you want to buy. After that, store them safely in your own wallet.
