Does Freebitcoin support all address types when I want to withdraw or do I have to chose a specific one, e.g., BIP84 (Segwit), BIP86 (Taproot), BIP44 (legacy), BIP49 (leg segwit)?
You can withdraw your fund to any of the standard Bitcoin address types except taproot.
Just note that if you want to make auto withdrawals, you can only use legacy addresses. That's because the auto withdrawals are made to your profile address and you can't use non-legacy addresses as your profile address.
Thanks. Si slow is fine or do you guys use instant?
