A man offers you this bet;

He will flip a coin and you call. The coin is fair.

If you win he gives you £2.

If you lose you give him £1.

If you win you can play on. Same odds.

(ie If you win he gives you £6 if you lose you give him the £3.)

You can only continue playing after a win.

You must invest all your money if you continue.

What is your strategy to maximise your winnings?

(ie after how many wins do you stop playing)

What are your average winnings with this strategy?

(ie if you played the game each day what would you expect to be up after a year?)
