Thanx everyone!
It is working. Like you said I typed exact amount, it was transferred, and fees were paid from my account and not from money I was sending. Nice!

BTC
How to find amount of fees when sending BTC? For example need to send 0.0409118 btc, Electrum wallet shows fee 15.8 sat/byte - so how to check which amount I have to send so recipient would get exactly 0.0409118 ?
