B can be withdrawn over 2 networks; BNB Smart Chain (BEP20) is the most widely supported (21 exchanges). Always pick a network the receiving wallet or exchange also supports — funds sent over an unsupported network can be lost.
Most exchanges accept crypto deposits for free — what you pay is the sending network's own transaction fee. The "Deposit fee" column shows a number only where the exchange explicitly publishes one.
Withdrawal and deposit fees are synced from each exchange’s official fee API or fee page (last sync 2026-08-29 00:53 UTC). USD values are computed at the live Bprice, so they move with the market. “paused” means the exchange currently has withdrawals disabled on that network. Network names are normalised — exchanges spell the same chain many different ways.
