Lost about 2% between Binance to hashpack hbar to hashpack Dovu

Withdrawing to hashpack 1%... 1000 U$D became 990.
Then changing from hbar to dovu on hashpack, there's a 1.5% slippage (apparently I can set this, what the heck is this and should I set it lower, maybe 0.3%?).

Anyway, at the end of the day I only got U$D 978 in Dovu. That's a lot to lose when hbar promises to be the most affordable. Opinions?
