If you cash out from Carbon, it will be a check from a third party, drawn on a Canadian Bank.
I just deposit mine and make sure I have it covered for awhile. I haven't had any problems in the last couple of years, but did have a couple of Carbon's checks bounce a few years ago. They (Carbon) made them good. It seems they were in the process of changing the third party.
I cash out for $300 to $350. I'm a micro player so it takes a few months to reach that level. Try not to let it get much higher in case there's another "Black Friday".
