We use Native SegWit Bitcoin addresses, which are ~44% cheaper for Transaction fees than legacy Bitcoin addresses. There's no minimum.

Exact costs are presented to you up front, before you go ahead, so there's no surprises.

Sending 2 Deposits isn't required, you can space out the time between deposit and send. Sending to multiple deposit addresses in the same Transaction also works and saves on fees.

Your Coins can not be traced back to you.
