Is CoinUp legit?
Couldn't verifyCoinUp is a working crypto exchange for coins and leveraged futures, but we could not confirm which company runs it or that it holds a licence for that trading. Its user agreement names no operator and its own pages point to three different countries, so a stalled withdrawal leaves you unsure whose rules apply.
Watch out for
- A withdrawal that waits until identity checks and a verified phone number are complete, as CoinUp's withdrawal rules require.
- Your account partly frozen during a risk review, which CoinUp's rules apply to suspected bonus abuse or multiple accounts.
- Holding a token CoinUp delists, as with its old CP coin, once deposits and withdrawals for it close on a set date.
Is your CoinUp withdrawal still pending?
We help you write it and it gets its own public page, so others checking CoinUp find it first.

How do I contact CoinUp customer service?
CoinUp customer service works by email and by ticket: write to support@coinup.io from the address on your CoinUp account, or open a ticket with "Submit a request" in the CoinUp Help Center, which is linked from coinup.io. CoinUp publishes no phone number, so be wary of any number found through a search that claims to be CoinUp support: fake support lines are common around crypto exchanges. Never share your password, two-factor codes or seed phrase with anyone. Put everything in one message: your UID, the asset and network, the amount, the order or withdrawal ID, the transaction hash (TXID) if there is one, and screenshots with the date and time showing.

Why is my CoinUp withdrawal pending?
A CoinUp withdrawal that stays pending has either not been sent yet or is waiting for confirmation on the blockchain, and the withdrawal record in your CoinUp asset history shows which. If the record shows a transaction hash (TXID), the transfer has left CoinUp: look it up on the block explorer of the network you chose to see whether it has been confirmed. If there is no TXID, the funds are still with CoinUp. At exchanges in general the usual reasons are an identity (KYC) check or security review on the account, or a token or network whose withdrawals are suspended. CoinUp posts such suspensions as announcements in its Help Center, as it did when the CP token was replaced by CPX.
Open a ticket or email support@coinup.io with your UID, the withdrawal ID, the asset, network, amount and destination address, and the time you made the request. Keep dated screenshots of the pending status and of your balance.
Withdrawal pending while the balance has already gone down? Open the case through our complaint process: our trained AI keeps coaching you on what to send CoinUp, when to push again and how to escalate if nothing happens.
Can I report CoinUp to the Consumer Financial Protection Bureau (CFPB)?
Yes: in the United States, the Consumer Financial Protection Bureau (CFPB) takes complaints about money transfers, virtual currency and money services, which covers a crypto exchange such as CoinUp. The CFPB generally expects CoinUp to have had the chance to put things right first, so keep a record of every ticket, email and reply.
Want that record in one place? Put it in writing here: we help you write the complaint to CoinUp in minutes, with every ticket number, date and reply in order.
Is Coin Up Digital the same as CoinUp?
No. Coin Up Digital trades from a different website and is a separate business from the CoinUp exchange, despite the near-identical name. A similar name says nothing about who holds your money, so compare the web address with the one you signed up on before you deposit or log in.
What do people complain about most at CoinUp?
So far consumers reported 1 complaint about CoinUp here, too few to show a clear pattern yet. Our research shows what typically goes wrong at centralized crypto exchanges: withdrawals that stay pending or under review, accounts restricted during identity (KYC) checks, deposits sent on the wrong network or without a required memo, leveraged futures positions liquidated in a fast market, and token delistings that close deposits and withdrawals for a coin.
