I think this would slow down the process of being able to sell bitcoin on their platform, as well as the ability to to debit customers' losses when they have leveraged losses.
Probably not so much, because they only settled accounts to the blockchain once per day. The exception being, if you bought bitcoins and immediately requested to withdraw them. That already took 15-45 minutes generally. Not sure how much this would really add.
The problem with BitGo is that they signed transactions that they should not have signed. I speculate that BitGo was signing transactions they believed to be "internal transfers" between bitfinex accounts, which I suspect are not subject to the limits that bitfinex set, although this is speculation.
They certainly signed transactions they shouldn't have signed. Even if they were internal transfers, that kind of volume (above, say, 20k or 30k) should trigger a circuit breaker. A telephone call, some kind of second step verification...something, rather than simply auto-signing for 120k bitcoins.
The kind of verification you/we all desire cannot happen at bitfinex, they just won't allow it, how else would they be able to steal your bitcoins next time? It was an inside job, blamed on hackers, the hackers were themselves, helping themselves to 120K bitcoins. Clever bitches. I hear they're preparing to re-open again. You fool me once...
