Could this be an always-profit Blackjack strategy?

[Colombo]

I just thought of this strategy now.

Say you want to make $5 from blackjack, and you have a bankroll of $80,000.

You could do a $5 hand, if you lose, do a $10 hand, if you lose, do a $20 hand, etc. untill you win. Obviously the odds are so so so small that you would not win at least once before losing $80,000 (15 hands in a row), and if you win a hand, you profit $5. Is there a flaw to this?
