Yesterday I made a mistake. I had 0.00959084 in my blockchain wallet. I run a faucet so I sent it to faucet deposit address, 0.00939084 - 0.0002 fee. After an hour I checked the transaction and saw it has been pruned by the network, at this point I had 0.00925 (guess they took additional fee) in my account, I went through the transactions and found couple of incoming transactions still not confirmed, but the balance was showing 0.00925 (before blockchain updated its wallet, unconfirmed transactions add up in balance, but when you are about to send bitcoins only confirmed balance is shown) so again I sent 0.005 to faucet deposit with 0.0002 fee and today morning when I checked this is what I got,

And surprise my wallet balance is now -0.00501604 so I guess a total of 0.0144 loss. I made a mistake with the first transaction, I did not check whether there are any unconfirmed transactions (if there are unconfirmed transactions why add it up to the balance while sending) and the second transaction was legit and still double spend. Would this transaction get confirmed? And more interestingly today morning I also got a authorize log-in mail from blockchain, someone tried to access my blockchain account.

So in summary, a case of double spend and might be a hacking attempt.

Aside:


First time I've seen an ad on that site which I frequent often. Noticed a 20% at Amazon so I clicked it to be greeted with ONLY a 15% savings, with no 20% savings to be found, but sure as hell if I order anything now and later, the advertise would enjoy a commision, perhaps on an ongoing basis.

Good observation, this was what I first noticed on the page too, the Amazon advert.

I thought that double spent is the a thing of the past in the space.

that's why should always prefer blockchain wallet only because its official and other all wallets like coinbase and xapo they might show that they don't take fees but finally they take double from you and you be not able to figure out when you money was cut by them. other 3rd party wallets a something like thief not all but few of them
