Ah, that can be a bit tricky. If you're seeing "not enough bitcoin" it could be for a couple reasons:

1. Unconfirmed funds: Maybe you got BTC recently but it's not confirmed yet.

2. Transaction fees: Gotta cover the network fee, and sometimes what you wanna send plus the fee is more than your balance.

3. Fragmented funds: You might have lots of tiny amounts spread out that add up on paper but can't cover a transaction after fees.
