FinCEN

[coin2013]

If a miner mines bitcoins, would a miner that is not registered as a money transmitter be able to sell them on an exchange that has registered with FinCEN (MtGox, Bitinstant, etc) or would they both have to be registered as a money transmitter?

Would a miner be able to sell bitcoins that he/she mined for gold/silver and not be considered a money transmitter?

Would a miner that mined litecoins be able to exchange them for bitcoins on BTC-E?

Putting mining aside for a moment; Is it legal to transfer funds to BTC-E and buy litecoins and eventually exchange them for Bitcoins on BTC-E when the price is right? Then find an exchange such as Bitinstant or MtGox that apparently has registered with FinCEN to sell the bitcoins for USD? Or would someone in the USA, not be able to use BTC-E because they are not registered?

Is it legal to buy/sell on what appears to be a registered exchange such as MtGox or Bitinstant?

Bitinstant is not registered with FinCen and why should they, they are in Europe.
There is a hint for you. In Germany profits from bitcoins are even tax free.

I just did a search http://www.fincen.gov/financial_institutions/msb/msbstateselector.html and it appears to me as Bitinstant as being registered.

MSB Registration Number: 31000005031107
