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.
so possible if you want to try. for the first if you want to buld bitcoin exchange you should learn more about exchange, how the team, and how to manage it because if you miss one of them you will fail like another exchange who can not survive with other exchange
my advice better to accept bitcoin and altcoin for your pet shop to collect customer and when your get a lot of customers you slowly build bitcoin exchange
