<prompt> Human: I currently have a chase freedom card I use for everything, and I love it. I make 100 in points every 3-5 months.I see offers all the time for some ridiculously lucrative offers for points with signup bonuses, and the rewards seem like they could possibly rival my current card.Im open to experimenting with some of these cards, but dont want to commit to keeping them if I dont like them. Most of them have annual fees, and I dont want to pay that unless Im getting significantly more back than my freedom card earns me now.Will it hurt my credit if I get the card, then decide to cancel it after 2-3 months? If so, how much are we talking here? I have pretty awesome credit and want to be careful not to mess it up.My main question is how much will cancelling cards impact my credit?Furthermore, while this isnt my intention, whats stopping my from signing up for ALLL the cards, banking on bonuses, and then cancelling?Or, for that matter, what if I dont cancel at all but just leave it as an unused card? Does it impact me negatively in any way then?  <response>: rchurning
