Looking for current advice

When the time comes to take some profits, I want to minimize the fees associated with selling. I am a Canadian with some sitting in a ledger hardware wallet , and some on the regular crypto dot com app. I have a handful of different tokens. Am I best to combine all as one specific token (maybe XLM?) then liquidate or transfer to a place I can sell with less fees? Which app/exchange/wallet will have low fees and is trustworthy? I know this has been addressed here before. I am wondering if the answers I saw are the same. Ndax was recommended and was Bitcoin well. I initially thought I’d convert what I wanted to cash, then add it to my crypto visa debit, then withdraw. That seems like a lot of unnecessary steps and fees. Appreciate the feedback, shared experiences and light roasting for using the app I currently do. Cheers.
