If I make a deposit today for $1,000 USD using bitcoins and it registers as $1,000 in my account, does it affect me if the bitcoin price drops by 20% the next day? I assume that once it shows up in my account as USD, I am not affected by the bitcoin price drop, or increase. So if it is a month later and the bitcoin price has dropped 40% since my original deposit, I won't lose anything necessarily since I am in USD. I'm just trying to understand this better.
