I want to buy a crypto coin. I don't have too much money. I want to invest something like 3k USD. Now I wonder what crypto coin should I buy and hold for almost one year. I want to hold that coin in this year, which is 2018 and I am planning to sell that in upcoming 2019. 2019 will be a big year for me, planning to get married

So please advice me and suggest me to the point.
Many many thanks in advance.
Buy EOS. This project will have ICO for another six months and only then the real price growth will begin, the development of the product will begin. It's a platform for ICO better than ETH
