Am I correct in saying that you (one person) were selling Bitcoin to other Dwolla users? Were there imposed limits? It sounds like you were a currency dealer via Dwolla, which I could see why they might not be too happy if you did not contact them before doing so and ask for guidance on regulatory requirements (with all the crap coming from the Fed lately on virtual currency, etc).
Yes, I had limits. The biggest transaction I ever did was $800. Normally they were much lower.
I see their side of things, but feel like their treatment of me was overly harsh.
