:)I downloaded a wallet for a cryptocurrency that I will leave anonymous. I loaded my coins and made several transactions. I open my wallet daily, but about a month after my last transaction, I opened my wallet and find that all these transactions had occurred that I had not made. But the curious thing was these transactions were backdated before other transaction
So sad to hear that news. Its a learned lesson for you and for us as well. From your story, maybe you downloaded a wallet from an untrusted sites. There are many cases like that now. However, your coins cannot be retreived. So next time, you should only use one wallet and if you download one, make sure that it is from the site of the coins.
