No , never calculated that , have you ? . . . . i did wonder if it was best to convert to tokens , and then from tokens to another coin , rather than coin to coin direct .
Every single conversion carries a 2.5% fee (they say it doesn't, but it does, if you don't believe it, convert btc to ltc then back to btc and see how many btc you lost).
Therefore converting from anything to tokens and from there to something else costs double the fee.
