Blackjack is easy to make money in too. If you have less than 15, or one of the contributing cards is an Ace High, then draw another card. If you have more than or equal to 15, stand your ground and hope you get lucky.
Then all you need to do is bet an appropriate amount of money. No more than a quarter or third of your total available dosh. You should win more often than you lose, so your money will just go up and up and up, and you can bet more each time if you want.
