A great platform that I would advise you to look at is https://nonbank.io/. I've been using its functionality for a few months now and have appreciated the speed and ease of transfers between cryptocurrencies. Commissions are awesome, and all operations are quite fast. By the way, I also created my cryptocurrency wallet here. It is easy to manage several assets in one place. If you want a simple but functional wallet for daily use, I would recommend starting with this platform.
