Yes you can withdraw up to 6 times from the money market account per month.
A money market account is just a savings account but the money market savings account pays higher interest on the money you have in the money market account so your money grows faster over the time it's in the money market account.
A money market account usually requires you to have at least $1,000.00 to $2,500.00 as a minimum balance in the money market savings account to keep it open.
