This fully answers my question, thanks!

I will actually move from kraken to binance. The binance table informed me that all deposits are free. So I can choose any coin that both exchanges have.
Then I found the kraken withdrawal fees https://support.kraken.com/hc/en-us/articles/201893608-What-are-the-withdrawal-fees-?mobile_site=true

It looks like stellar is almost for free. But it has a*. So perhaps there are some small side Letters, but I don't see anything.
I think I will go for ripple. 0,02 from $2 is only 4 cents. No need to search any further 😀
