It is wise to invest in different coins but I suggest that you split it into 4. The forth one would be a non crypto currency investment or an investment to  build a small business that transacts with the current money in your country. Also, if your are going to do trading you read a lot of books because in my experience I also said that I was going to invest for a long term but I cannot help to trade daily and as a result I lost 50% of my investment.
