Despite the benefits of just gambling alone, there is also the beauty of gambling with other people that is undeniable. In this context, do you still prefer gambling alone?
There is a strategy you might be missing while doing it alone and also the strategy you use while your associates are slow lacking. It does not mean that you'll be getting their predictions all the times but at some point, you'll gain their view on how they come up with their own strategies. You might be stocked on relying on your own strategy for a period of time not knowing that game plan and players or other conditions have changed, associates will let you know all of these.
In conclusion, I'll say that sticking to your strategy is good but also associating with others too for their own strategies is pretty better, using their method of predictions or maybe bet options to add to yours.
