But you know that how much gambling is risky for you? you can loose your investment. And if there is a competition between gambling and investment, i will choose investment because gambling is too much risky and winning chances are very low so choosing gambling will lead you towards a big loss so i would say if you want to loose your money within hours, join gambling
I don't think anyone can earn money in the long run just only based on skills in sports betting. You also need a luck to win always so it is not a good way to grow your money but sometimes you can bet for fun on sure matches to enjoy your success. To grow money investing is always good compared to gambling.
