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.
The basic would be choosing a coin with lower total supply which has low price. Better take a look of coins that is to be introduced in the market, also try to join an Initial coin offering (ICO) there were good offers out there. Try to make some good read of the project, there were white papers available that is translated in your language. Coins that has lower price will allow you to get greater volume, just in time (even for just a year) you will see that coin fully grown. Most coin that was and is to be introduced are more better for long term.
