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.
You should try and see EOS, it has a good fundamental and I think the price of it will go up to $100 until next year.
