I've gotten pretty lucky the past few weeks and have wound up with a decently large sum of money (for me at least). I'm pretty young so I'm not that educated on how tax laws and everything works, but how much money could I deposit in the bank without raising eyebrows? Should I just keep the cash in a safe or something? Been in the market for a new car and I've recently won enough combined with my actually earned money to buy the car without any note, but scared that might be a bad idea.
