Did you send from different kind of wallet? I think the 0.002 is for transaction fee, isn't it?

I think you may have a malware if 1APG.. does not belong to you.
From the transaction ID you sent 0.002 to 1APG8xxd not 1AF8 as you intended.

And 1Apg has made other transactions after receiving your 0.002 BTC. If you haven't made any other transactions then that address does not belong to you.

It seems like there were 2 outgoing transactions from your address 3BMSebkKfRjJcFGp3moofZ2oVnDaFp8hm6, both trying to spend the same input.

Quote
1s. TX [2017-12-11 15:35:46]
0.00086661 to 1FAsfPJ5WCE6N9aqjzUqnuwEwEmLLzERru
0.002 to 1Apg8f9n2CawhNdVSyKUmRgigv8qXffJgy

2nd TX [2017-12-11 18:46:27] (with higher fee)
0.00047311 to 1FAsfPJ5WCE6N9aqjzUqnuwEwEmLLzERru
0.002 to 1Apg8f9n2CawhNdVSyKUmRgigv8qXffJgy
https://blockchain.info/de/address/3BMSebkKfRjJcFGp3moofZ2oVnDaFp8hm6


Do you remember at what time you sent your coins? Whether it was ~15:30 or ~18:45 ?
If it was at about 15:30 and you didn't try to resend the same TX with a higher fee, there seems to be malware on your pc.
In this case i would recommend to immediately clean your pc with an antivirus (or better: completely new setup) and move out all your coins ASAP.
You should regard every password and every private key which has used/stored on this pc as compromised.

I modified first transaction to offer a higher fee
I haven't made another TX after that nor 1Apg is part of my addresses, is that means someone else got my .002 and that's it? Sad

Since you are not in control of the address 1Apg8f9n2CawhNdVSyKUmRgigv8qXffJgy this means yes, they are 'lost'.
Regarding that this address is one of many 0.002 balance - address sending their coins to 18cb75s97h3eTmhHb2DiszLqWsUZShovVT [1] and 1PLBjywFwsz5UeWofns5EDpYf6ceT2AHcY [2]
Since both addresses have 181 respectively 550 transaction all composed of 0.002 and 0.0005 inputs i guess this is some kind of malware trying to branch some money into the attackers wallet.
Basically like salami slicing [3] just with not so small amounts.. You should check your PC for any kind of virus/trojan/root kit/..

I will wager 0.01 BTC that the OP has sent coins from an Electrum 2FA wallet... and has not realised that Electrum 2FA wallets require prepayment for 2FA transactions. The 0.002 BTC is the prepay fee for 20 "credits".

How much does it cost?
TrustedCoin charges a small fee to co-sign transactions. The fee depends on how many prepaid transactions you buy. An extra output is added to your transaction every time you run out of prepaid transactions.

Costs depend on how many prepaid transactions you purchase at once (which is configurable by clicking on the TrustedCoin shield icon in the lower right of the Electrum interface).

Pay every 20 transactions:   0.0001 BTC/tx        0.002 BTC total

Pay every 100 transactions:   0.00005 BTC/tx        0.005 BTC total

Totally agree, thats what happened.

The address the 0.002BTC was sent to, was later used as input together with other 0.002BTC's and 0.005BTC's.

Electrum is a nice wallet, I have used it in past. 2FA stands for 2 factor authentication more info on their docs website http://docs.electrum.org/en/latest/2fa.html

First ALWAYS INFORM YOURSELF, specially since you are dealing with digital money where you are your own bank, understand the risks. DOn't be like I am here for 3 days - it is okay but try to learn a bit more about the matter before you jump straight to it. Some wallet list: https://bitcoin.org/en/choose-your-wallet

You can also try jaxx , exodus they are popular wallets that support many coins, be aware of malwares with these. Best and one of the most secure wallets are hardware wallets such as keepkey, trezor, ledger nano etc. - https://en.bitcoin.it/wiki/Hardware_wallet

If you are certain that you won't move your bitcoins for long period of time check out paper wallets https://en.bitcoin.it/wiki/Paper_wallet they are also secure since you generate private keys and addresses on your computer - advised offline with live OS booted from USB/CD for extra security.

Create a "standard" wallet in Electrum...

and next time, take the time to READ every window that pops up... When you setup a Wallet with Two Factor Authentication (2FA) wallet, it clearly explains how it works using TrustedCoin and that there are fees involved. Wink
