Anyhow, you can see how no coins rushed to the exchange after the Dwolla news. Fiat rushed out, but BTC did not rush in - which makes sense, if you use Dwolla there's no point in exchanging your un-seizable currency for seizable fiat.
There is if you don't like losing money as BTC prices fall and you want to buy low. Fiat is fine inside of Dwolla, for the moment. There is nothing illegal about Dwolla. They are in compliance of US regulations. (Or so it seems) But this series of recent comments is really two different conversations. One of those who want to stash BTC in wallets and go long. Totally fine and those who want to make money buying in low. Also fine. Apples and oranges really.
Additionally, they don't have to "seize" BTC's. All they have to do is block the flow of fiat in and out, and BTC's becomes worthless. How some people are waking up trying to hold on to these delusions is simply amazing. I call it denial. Bitcoin is only as strong as the fiat it can be converted into.
