I think someone stole 100 units (tokens) of ethereum from me! I am a novice to the world of cryptos and last year purchased 100 tokens on the Coinbase exchange. I kept the crytpo on the exchange for almost a year and watched it grow 30X.
I kept reading it is safer to move cryptos to a digital or paper wallet and finally got around to doing so. I moved my ethereum to a digital wallet using MyEtherWallet. About 4 hours after my transaction was approved on the blockchain, it appears that a 2nd transaction moved my ethereum out of my account into some other account and MyEtherWallet is showing my wallet has a zero balance!!
How could this happen! I did not give my private key to anyone and only wrote it on 2 pieces of paper I keep at my residence.
Is it possible to effect transactions on the blockchain without a person's private key?
