I guess fees are not only the concern the crypto currency exchanges what should be more concerning is security and safety of the funds that we are trading over them. Now at any point we will always be holding more than 1000 USD over the exchanger with different coins and tokens. Thus it must be a secure exchanger and we better not be victim of hacks and leaks that keeps happening these days.
For me it doesnt matter if the fees are 0.1% or 0.05% by using their tokens because thats just tiny fraction of the what we are trading and thus it should not be very concerning for us at all. Thats just my thought regarding the crypto currency exchangers.
You prioritize security rather than fee issues. I guess that's also a rational reason. As long as we feel comfortable, I don't think there will be a problem. Long term traders do not feel the impact of the fee though. I may have the same thoughts, because I also do not trade too often. And I usually choose to use an exchange that has stood for several years and has proven its credibility as a good exchange. I'm worried about some things because of the emergence of too many new exchanges.
Main point I look at when choosing an exchange (which I rarely do, I have been in crypto for 6 years now and only used 3 exchanges total for altcoin trading and only used 1 exchange for local fiat cashing out since I started) is the trust aspect. If you see the news there has been a lot of people who complain about their money being stuck on some exchanges.
Coinbase is one of the biggest exchanges in the world and they have been the unicorn of startup world in silicon valley and started a new shop in ireland as well to go global but in reality there has been a lot of complaints on reddit where people talk about how coinbase kept their money without a warning and people had trouble getting their money back until they complain to SEC or similar places.
If even coinbase is doing this than it means you need to be really really careful with exchanges, thats why I usually try to do my job quickly and try to get out quickly and not hold too much funds in any of them but if I am going to do it I try to select the best known and trusted ones.
