However, credit card chargebacks are pretty uncommon
Ahahahahaha nice joke
Because it is a joke, am i right? You cannot be serious
Uhh, no, actually. My wife runs an online store, she's done thousands of transactions and has had less than 5 chargebacks.
It's not like it's any different than selling something physical... if someone buys an $800 stereo and claims it never arrived, what recourse do you have? Bitcoin is actually the *best* possible thing to sell via credit card, because you can
prove you sent it, so you should be able to trivially win any disputes about whether or not you delivered the goods that were purchased.
BTW, I have purchased bitcoins via Coinbase, since as you said, they are the fastest... though there's a 4 day waiting period between purchase and receiving the bitcoins (which I understand, they're waiting for the transfer to clear), and at least that way you can instantly get bitcoins at about the market rate. The bad press they have gotten on here and elsewhere is a little disturbing. I don't really believe they're intentionally screwing people, since that's a surefire way to lose any credibility... but it's still not good seeing occasional bad reviews.
