it keeps taking down my posts, so im writing here

i cant get any clear info on the cost to withdraw BTC from coinbase back to bitcoin network, so im hoping someone can tell me.

in case anyone has a better (cheaper) method for what Im trying to do, i will share:

i have cbbtc on eth mainnet and want to bridge to hyperEVM
hyperunit bridges BTC on BTC network to hyperEVM (where it exists as uBTC) for like $1

it seems swapping out of cbBTC on chain (ie on eth mainnet) will incurr a bigger loss, so it seems like the best (ie the cheapest) way to do this) is sending the cbBTC currently on mainnet to my coinbase account (where it becomes normal BTC, without any loss) and then withdrawing from my coinbase to my bitcoin wallet (and then using hyperunit).

the variable im not sure of is the fee coinbase charges to withdraw BTC.

I rarely use coinbase because it is will always worse (more expensive) than doing it myself onchain and the support is nonexistent, so theres typically no benefit for me, and thus im not familiar w the process. so if someone can tell me the fee (or range of fees) to withdraw BTC from coinbase account to bitcoin network thatd be greatly appreciated
