Bitcoins and transactions missing I had a wallet which had approx $660 worth of bitcoin somewhere around 0.05 BTC and all of a sudden it has vanished and my transaction tab shows nothing.

I have put my receiving address into the block chain and it shows that a transaction sometime in March of 2019 was made and I didn't make any transactions in March of this year. How odd. Anyway this has blown my mind and I don't know who to ask for help or what to do ?

Any ideas or can someone be of assistance? I really don't know what to do. In addition, I was thinking that maybe bitcoin had plummeted on the market and maybe it lost value and that's why maybe I have none but to be fair there was enough bitcoin in my wallet but no nothing.

Am I doing something wrong and it is safe for me to paste my receving address here for someone to take a look or is that a bad move ?

I only use my bitcoin to pay for VPN and it does show that I renewed my VPN in august which is when I did make a transaction so why it is showing a transaction in March 2019 makes no sense whatsoever.

I've read that something does cause bitcoin to appear as vanished but to be fair I've re-synced which took over 24 hours and I created new receiving addresses which I read can sometimes re-gig the system and your available bitcoins appear.

Nothing?

Any ideas ?
Thanks

TL;DR:  Your money has been stolen. There is nothing you can do that has any significant probability to recover your $660.

The thief got access to the private-keys stored in your wallet.

One possibility is that someone gained access to your wallet and stole your money.

One recent issue was with the Electrum wallet.

However, if you have a PC wallet or access an online wallet from a PC it is always possible that other malware on your PC stole your passwords and used them to access your wallet, steal money and finally erase logs and data to cover their tracks.


  I have put my receiving address into [a] block chain [explorer]


Most modern wallets are HD wallets that create a new receiving address for each transaction.


  I created new receiving addresses which I read can sometimes [make] your available bitcoins appear.


I've not heard of this, it would have to be a bug in a specific wallet. In general I would be surprised if this helps.

If you found unexpected transactions in a blockchain explorer, it is unlikely that there is a fault in your wallet software. More likely you are a victim of theft.

If your wallet is misbehaving. One solution is to make a careful copy of your seed-words or your private key (you should have these already in a safe place), then use those on a fresh computer (or phone etc) to download and install the wallet software from the only genuine trusted website and make a new duplicate wallet and let it synchronise fully. You don't need to erase your old wallet until the new one is working fully.


  it is safe for me to paste my receving address here


Yes. 

There are potential privacy issues if you only use one receiving address. Anyone can see a list of all the transactions made involving that address. But it doesn't give anyone any way to access your money.

You can also safely publish a transaction id and the name &amp; version number of your wallet software (e.g. bitcoin-core 0.18.0, electrum 3.3.4, ...)

Never give anyone your private key, your seed-phrase / recovery-phrase or the password to your wallet or online wallet or account. Changing a previously disclosed password does not re-secure your wallet/account.




  Also this is what I read regarding created a new address can sometimes show balances again: reddit.com/r/Iota/comments/6sim7o/ 


That advice relates to IOTA not to Bitcoin.




  I'm positive that I never used bitcoin this year


Everything suggests your Bitcoin was stolen.

I wouldn't use that wallet again and I wouldn't use that PC for any new wallet or any further financial activity again. Even after zeroing the disks and cleanly reinstalling the operating system, I'd worry about BIOS malware, infected USB devices, etc.
