If they are available in the country where you live, you should check out Trade.io and Crypto.com.  Trade.io has a feature called Liquidity Pool where you can stake their token and receive interest payments in various cryptos.  Liquidity Pool isn't really a trading tool but they do have maker and taker trading with very low fees.  In fact they have zero deposit fees, zero maker fees and very low taker fees.  They also have very minimal withdrawal fees.  Likewise Crypto.com has an investment piece where they do all the work for you.  You simply deposit the crypto and they will buy and sell and trade as they see fit within the guidelines you set out.  I hope one of those helps you out a little bit.
