BTC/USD after a 50% retracement to the 9$ support rebounced nicely up to the resistance at 12$. As indicated in the chart i’ve my Alma weekly moving average at 11.93$, in the last six weeks the BTC/USD has never been able to stay above it, thus this average is showing to be a reliable indicator for the long term. A breakout of this average could be the first warning for a long term reverse of the actual downtrend.
Finally, I should like to say a word or two on Tradehill, this exchange was born as a valid alternative to MtGox but so far it failed to meet expectations. Why? well because if you look the daily volume activity it is not growing, always beetween 1000 and 2000 bitcoins exchanged every day on average; numbers never lie.
Mtgox is and will remain the leading exchange for a long time ahead.
