At this point, it is just a renaming of an existing section. You would use your Funding Wallet in case you want to buy or sell crypto with peer-2-peer.
For example, P2P mode allows you to purchase crypto directly from private sellers with lower fees.
In addition, Binance pay, card and gift balances are a part of this section too.
Apart from this, new promo info can be found in the referral section. Your new referrals will be able to get gift boxes containing up to 500$ in prizes. This is a good chance to give it a try if you haven't already. This option will be only available until 18 of January.
