Not to be a pessimist but I think it won't happen this year. Based on how things are going for Bitcoin at thid moment, I think its not possible within this year especially if there's nothing will happen which is positive or in favor with Bitcoin. It is unfortunate to see the market value of Bitcoin is suffering right now affecting its market cap. But it is still a long way for this year so I hope things will go in favor with Bitcoin on the remaining of 2018.
