Definitely skills. Do you think the best investment firms are profitable from just luck? Of course not. It’s the same with sports betting.
In 2017, it’s important to think outside the box for ways to win at sports betting. Look to other industries to see how people are making money, and borrow their methods. The best example is the stock market, like sports betting, there are always winners and losers, and there is a huge amount of money flowing through.
It is a combination of both as any skilled sports bettor also needs luck and it goes the other way around as well (no matter how lucky you are you won't get anywhere without skills). But for constant profit in the long run experience and knowledge about the betting industry are the most important things. You can check out 777score.co.uk/ for advises.
