ALERT: One new wallet was added to Apple Store which is most likely a scam wallet. Please be advised.

Edit: I was originally going to report two scam wallets, but it appears one was already taken down. It shared many of the same characteristics with the below. Please help report it if you can

I and others have helped expose nearly 25 scam wallets on iOS (which have all been taken off the store). I very strongly believe the below are scams and you should proceed with caution. Many of the below characterists were shared by all the other scam wallets, and there were a few earlier scam wallets that we KNOW were designed to steal bitcoin.

Cosmo – Wallet for Btc

Seller: Tham Duong

© Wallet

Reasons why I believe it's a scam:

  • It says it's © Wallet (it literally says copyright wallet in the description)

  • Description of the wallet is only half english.

  • Nobody knows who this developer is, it only links to a Github page

What makes an unconfirmed tx ‘suspicious’? (likely to be replaced or never confirm)

When looking at Bitcoin unconfirmed transactions, I’m trying to distinguish between txs that are likely to confirm (whether that be in the first next block or in 2 hours) versus txs that are likely to be replaced, or never to confirm at all.

Obviously, txs with the opt-in RBF flag fall in the latter category.

But I guess there are other criteria, such as:

  • having an extremely low fee, or even zero fee.
  • Having lots of dust outputs.
  • Depending on unconfirmed inputs.

Anything else I should take into consideration? What other factors could make a tx less likely to end up confirmed?

For example, besides dust output, do dust (i.e. many small) inputs make a tx less sure to confirm? (other than more inputs causing larger tx data, thus resulting in a lower fee when measured in satoshis per KB)
