Well I am always afraid of anything betting and gambling because it may not be able to generate any reasonable profit , I can only be able to engage in this if I am able to see people that are making constant money from it perfectly without losing then I can consider it as a business but in most cases a lot of people that are engaging in these are always losing their money and it will be very rare for you to see someone that is making constant profit from betting or gambling.. if it is profitable people will always like to go into it.
