Hi there.  Out of necessity, as I needed to withdraw some spare tokens I had lying on some popular exchanges, and since I haven't been able to find a simple exchange withdrawal fee comparison on the internet, I've put together a table so you can compare these and choose the cheapest one in each coin/exchange scenario. I know this could and will get outdated rather sooner than later, but meanwhile I hope it can be useful for some people.

I chose some popular coins as this list is not intended to be exhaustive. I will add more exchanges once I can find some time.

Hope you find it useful.

Note: I can't easily get access to Liqui exchange  withdrawal fees, as you need some balance in each coin to be able to see the actual fees. If someone could contribute in order to compete the missing data I would appreciate it.
