I have an online wallet at localbitcoins.com (address 12pHFR5yv2KGqck5N8teb5MgoRtzAgLRn2).
I made three transfers to it, for a total of 0.5 BTC + 0.5 BTC + 0.3031 BTC = 1.3031 BTC.
Blockchain.info did show my address receiving coins. However, it is showing my address sending coins to several addresses after receiving them https://blockchain.info/address/12pHFR5yv2KGqck5N8teb5MgoRtzAgLRn2:
Is someone using my online wallet at localbitcoins.com to withdraw money?
