For example :minor clarification above in red.
we're at a Income and Dividends phase. You have $6.000 money left
at that moment after collecting your income. You have in front of you 1X 5 bonds card and 4x 1 bond cards.
You then have to pay $9.000 as dividends for all the bonds you have issued until now. But you can't pay, so you have to issue 1 bond (not more) to take $5.000 from the Bank. You can now pay $6.000 + $3.000 = $9.000, and keep $2.000.
You don't pay dividends on the 1 bond card you took to pay your dividends.
Hope that helps.
