It's good what they're doing. How many exchanges have been run under questionable practices? Not just Gox (extreme example) but almost every one has had some irregularities. Just when you think an exchange is legit suddenly you find out its run by one guy from his moms basement or they simply vanish without a trace... What straight world financier would want anything to do with any of them.
The winklvii may have made a deal with the devil by going legit regulated and public, but if they continue doing things the proper way and above board they could indeed attract the old boys who otherwise would never dream of getting into btc.
There's a reason for regulation and its to keep things honest... In theory anyways. Besides, would you rather deal with tools like mark karepeles?
I hate it, but I have to agree with you... After the MtGox fiasco, people already have preconceived ideas about Bitcoin, and to offer them a perfectly legal option to enter the
market, could be the solution to bring in some of the big boys. It's a bit of a sacrifice, but it's the right move under the circumstances. We do not need another fly-by-night
operation like MtGox, spoiling the party for everyone.
