The investment portfolio is something we should all do because this will make the job of choosing a better investment, more objective. With CAD 500 you can invest in many currencies and form a long portfolio and I recommend investing about 6 to 8 coins that have a good chance. 
6-8 coins it is not enough if you look at the market as it is today. its very difficult to choose exactly 6-8 coins. in one area, there may be 5-10 coins that compete with each other. and 2-3 coins will seem promising. it is best to invest in 10-15 coins. so your chances of earning will be higher
