Founder of ethereum warned users via his official twitter account about intruders who wanted to steal money using an email [email protected].

@VitalikButerin there's a scammer using a [email protected] email to try to steal funds.

One user receives a massage from that address in which “Buterin” asks for 250 ETH for one day in order to donate them to Metamask.

I do not control [email protected]; any email you receive from that address is a scam. All my email addresses have .com or .org domains.

Right now Vitalik Buterin is participating in Devcon4 in Prague, an annual developer conference that is devoted to the ethereum blockchain.
