dividend certainly not always guaranteed to increase every year however, once a company has the reputation of delivering reliable dividends that increase over time, then the company start working hard so that it dosen't disappoint the investor.If we start with a penny on day one and double our"account" each day, we would be a millionaire within 28 days.

Still i can't say how much it would be worth
