BTC.b on Avalanche is a token representing BTC on Avalanche that was bridged from the Bitcoin (".b") blockchain via the Avalanche Bridge.

For example, when sending BTC over the bridge to the Avalanche Network, it will appear as BTC.b once the transaction is completed.

Note that sending BTC.b back, is the same process but in reverse, resulting in BTC.b turning into BTC.
