Billy, the IRS requires you to pay taxes on income (not assets), regardless of whether you deposit it to a bank account or not. Please forgive me if I'm wrong, but the questions you ask appear to indicate that you are attempting to avoid the detection of income that you have earned. If you are not doing so, the only dollar amount in a bank account that would be of concern to you would be the limit of FDIC insurance, which is far greater than $10,000.
