Tips on how to keep as much money as possible with a big sale.

Hey everybody! I need some advice.

I'm about to sell maybe about 70k euros worth of crypto and convert to FIAT (euros). With these kinds of amounts, I realize that difference in fees can have a pretty massive impact, in the hundreds or even thousands.

I do have experience with crypto, currently holding all of it in a ledger, but I don't have enough technical knowledge regarding the really intricate stuff like slippage etc.

In order to keep as much money as possible, it seems like Binance is mathematically the best option for me, now I'm just wondering if there are any other things I should keep in mind.

I was planning on transferring everything from my ledger to binance, then execute a market order on a BTC-EUR pair and get the euros this way, from within their trading view.

Any recommendations or things to watch out for? Obviously a bit paranoid as this represents a lot of money for me.

Cheers
