When you make a purchase using Coinbase, the funds you spend are first transferred from your bank account to Coinbase. They are then held in your account on the Coinbase platform.
How long these funds are held depends on a few factors.
The first factor is the type of purchase you made. If you used a credit or debit card, the funds are generally available immediately.
If you made a bank transfer, the funds can take 1-5 days to become available.
The second factor is whether or not you have verified your identity with Coinbase. If you have not verified your identity, Coinbase will place a hold on your funds for a longer period of time.
This is to protect both Coinbase and its users from fraud.
Once your identity has been verified, the length of time your funds are held will depend on your payment method and country of residence. For most users, the funds will be available within a few days.
However, if you live in certain countries (like Nigeria), it can take up to two weeks for your funds to become available.
In conclusion, the length of time that Coinbase holds your funds depends on the type of purchase you made and whether or not you have verified your identity.
