The transactions paying to you were confirmed, but there have been a few subsequent transactions moving those coins to new addresses: txID 4d88a869b354b64a14d384939d1d801966733b892c07c189e9ceace3a57c49bd and then txID cb1fc617b635f851d79123f5e1fe16c98948c421445007ca11a2050ed4213355. The coins now reside at address 14qCMrBxt21idaa9FzZ5VBUKpy3rztXEvF. --- I am unfamiliar with bcoiner wallet, but a quick search reveals a help page on their site. If you did not make those transactions I would recommend contacting them to see if they can help.

In general, I would recommend using wallets that are well-known and well-reviewed (and most definitely, open source!). Bitcoin.org has a list of recommended wallets that is a good place to start from.

Happy to help. I do hope that you have not been scammed, and considering a lot of the world is celebrating holidays right now, maybe the support staff is just on vacation (wishful thinking, maybe). But otherwise, it is definitely best to stick to known wallets, and make sure you download them from trusted sources (or build from source code yourself).

thank you for the optimism. I hope so too. It's still writing in my wallet that I received 450 dollars and I didn't send it anywhere, so let's hope! Thank you! I will be much smarter next time!

@Duckduckgaga I would recommend avoiding the blockchain.com wallet. See https://bitcoin.org/en/choose-your-wallet for some well-respected choices.

> **Whats happening here**

As others have commented, the money was received by the address in your wallet but was subsequently spent.

Since your wallet doesn't show the expected balance but also does not show the spends it seems there is some flaw in the app or in the service behind it. Whether this is a malicious flaw is impossible to say.

Since you didn't spend that money, someone else must have. That suggests the wallet has been compromised or the underlying account in the bcoiner service has been compromised.

Since bcoiner support have been unable to resolve this to your satisfaction, it might be prudent to avoid putting any more money into this wallet.

The bcoiner wallet is not an app I personally would use for the following reasons:

* **Unresolved woe** - There are several stories similar to your own on this website. All wallets have some such stories associated with them but most also have some history of such problems being resolved or being found to have a more reasonable explanation than possible theft by app developers.
* **Suspicious review profile** = Profile of reviews on Google Play seems suspicious to me. There are many 5-star reviews obscuring 1-star reviews (mostly similar experience to yours) and *not much in between*. Either this is a great wallet with some flaws or somebody is submitting fake 5-star reviews in a way that Google Play doesn't detect. The developers responses to the 1-star reviews are rather uniform and unhelpful. The evidence here is very weak, but I'm inclined to be cautious when choosing software that has control over money.
* **Custodial?** - I have seen [allegations](https://walletscrutiny.com/android/com.bcoiner.webviewapp/) that this is a [custodial wallet](https://bitcoin.stackexchange.com/q/81240/13866). I would not want to use a custodial wallet.
* **Not open-source** - It is proprietary closed-source not open-source, I prefer open-source wallets.

In the end I suggest you make a decision based on the quality of support you receive from bcoiner developers and from the community of bcoiner users.
