  • I meant bcoiner wallet. Its a scam isnt it? 450 dollars!!!!! – user101526 Dec 24 '19 at 19:08
  • 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. – chytrik Dec 24 '19 at 19:09
  • 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. – chytrik Dec 24 '19 at 19:10

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 that this is a custodial wallet. 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.


It may be worth searching this site for other questions about bcoiner and using that information to help you to decide what action to take and whether to select a more popular and better supported wallet app.


Appendix - Google Play reviews:

  1. Bcoiner - too good to be true? surprisingly polarised? bcoiner ratings barchart

  2. Mycelium Mycelium ratings barchart

  3. Blockchain (their non-custodial app, not their custodial wallet service) blockchain ratings barchart

  4. Bitcoin Wallet (Schildbach) schildbach ratings barchart

  5. Electrum - A formerly well-regarded wallet afflicted by a security flaw and a badly received recent update? Electrum ratings barchart

I found it revealing to actually read the reviews sorted by newest first and get a feel for the range of feelings expressed and the variety of subject matter and writing styles. Doing this for several wallets gives you an impression of what is normal and what is not.
