When transferring some USD into that coinage we all know and love, most prefer to put a couple dollars extra into the bank for security if the prices change. I have a question about this (my intuition is saying this belongs on /noobs, but, it'll largely go unanswered)...
Say the price is 0.54BTC - and it doesn't change a bit. Couldn't I just bust over .54BTC no matter the exchange rate, and be able to purchase the listing?
...Maybe someone can walk me through this logically. I don't think the math is adding up.
Prices are set in USD.
