In my opinion. The best investments depend on your ability and knowledge. Before you enter to the investment, you should always be prepared. If you dont know your investment, there are a lot course on the Google or you can buy books, attend a seminar to improve your ability and skill. The best investment nowadays is bitcoin because the value is on the dip. Bitcoin can also buy the minor coins like bash, Ripple, and others. Good luck have fun on your investment.
