Bitcoin7 has worked alot better for me in the past week than MtGox. MtGox didn't bother to complete Liberty Reserve withdraws that I ordered about a day before they had the problems. There is no reason why MtGox can't send me Liberty Reserve that has nothing to do with and predates any hacking attempt. I have done several LR withdraws from Bitcoin7 in the past few days and they have all been within 3 hours or so. That is much better and more professional in my opinion than MtGox who does LR withdraws in 3 days or as long as they feel like keeping you waiting. I'm sure Bitcoin7 has some security and software flaws as do all websites. But right now I think there biggest problem is that they don't have enough users.
