The exact figures depend on the amount of money you are willing to allocate for this business. Of course, the larger it is, the greater the profit. However, when viewed as a percentage of the allocated amount, the one on the large amount you can earn a percentage slightly lower than in the young. This is because the restrictions come into force bookmakers on maximum amounts. For small amounts of restrictions virtually no bankroll (allocated amount of money) will increase very quickly. Earn sums are different, but you can safely count on a 30-40% increase in the bank every month. How much time will you devote to this depends on you and on the available amount of betting. At first it may be missed, and 1-2 hours for the job. When bankroll will be more, you can give this more time. The best part is that the income you receive will be immediately visible in the calculator. This will help you decide on how much time to devote to this.
