/biz/ - Business & Finance

So /biz/, I recently acquired my first credit card, which comes with 0% interest for the first 12 months.

I've been thinking that it's possible to make money on this offer, but it seems to simple to be true.

>all spending on credit
>get more 0% cards to avoid hitting limit
>direct debit for minimum repayment each month
>bank what you're not paying them immediately and accumulate interest/dividends/other income
>Pay off cards in full before offer expires

And voila, you've made money from credit.

Is this a good idea? Will it hurt my credit score?
