I have frequently been moving around coins in the past months, between exchanges and wallets. Transaction fees can differ a lot I noticed. I also calculated that in some cases it would be more cost efficient to exchange a coin with high transaction fees into a coin with low transaction fees before sending to another exchange (and then change them back).
Is there any overview on (current) transaction fees for let's say the top-100 cryptos?
Transaction fees can be variable for some while constant for some and it also depends on exchanges that may or may not leve extra fees.
