Noté q ese foro q creó ud esta ubicado en Argentina. Capáz q sierve como un foro para los temas de BTC en Argentina. Yo sé BTC es muy popular en Argentina debido el crisis económico y las reglas duras contra la exportación de ARS del país.

Yo tengo interés en vender BTC en Argentina desde EEUU, y quiero colaborar con unos Argentinos para hacer un negocio así. Capaz que hablamos en su foro.

I travel to South America and speak Spanish, but I live in US.

I bought my first BTC on Coinbase with a straight-up bank transfer. I opened an account on Bitstamp at the same time to compare, but went with Coinbase because they're based in the U.S. The significance is that I didn't have to provide photo ID to get verified. Also, I thought if there was a dispute, I might have better chances of resolving it with a U.S. company than a foreign one. I might buy my next BTC from Bitstamp, which is based in the U.K., if there is some advantage to buying BTC there.
I opened another account at my bank to use for transfers with BTC exchanges, and transfer money between the two. That way if the account is somehow compromised (user/pass hacked), my paycheck and rent money are safe. I check both Coinbase and my bank account every 1-2 days to make sure everything is the way it should be.
Now that I've got a little experience at buying, I'm looking at selling to those who can't or won't do the bank transfer process. It looks like there's a market out there for that, from what I've seen on sites like localbitcoins.

I went to Bitvisitor and got redirected to their 'abuse' page, which displayed this message:

"The ip you are using has been identified as suspicious. You will not be able to use our service."

I was/am using Witopia VPN - how is this "suspicious"?

In the short time I have been studying Bitcoin, I have realized that it is not one but several things - part currency, part cryptography, part social experiment - which is why I have become more and more intrigued by it. I have already learned much from this forum, and I put it at the top of my Bitcoin bookmark list. So I will thank the more senior members here in advance for answering my newbie questions.
