That is why it is always advisable to choose the exchange where the fees are not hidden. The rate which can see should be inclusive of all the fees. Some exchanges have there fixed withdrawal fees as well. Can you please tell us on which exchange you are seeing these fees so that we all should be aware of that exchange.
all total nominal transaction calculations after deducting fees are clearly seen from the column to be confirmed manually, there is no exchange that hides it, the topic here is about the different fee amounts of each coin.
I will never recommend to convert your BTC with any of Alt coin. There is no alt coin that can compete with BTC in near future. If you have extra cash buy some Alt coin to built a portfolio but dont interchange ur BTC with Alt coin.
the context is cheaper witdrawal fees besides btc (trx, ltc, xrp), and also the effect on transaction waiting time, do you even read the first page?
