Ive got a pet shop and I wanted to accept bitcoin and alt coins then I was reading about becoming a bitcoin exchange ... is this possible? I understand its worth goes up and down.
Pet shop ad bitcoin exchange would have no actual connection.
You can try to sign up on some payment gateways like coinspayment, coinmama, etc and start accepting local payments by generating invoices.
Creating a exchange is not really a easy task and you would need a lot of money to make it start and regulate.
