Bitcoin is trying to stop its sales started from the first day of the week. And now it’s showing cautious moves just before the US Secretary of Treasury Yellen’s speech about cryptocurrencies. Technically, we expect Bitcoin to increase as long as it stays above 42 500 indicating the diagonal lower band of the descending channel. As a result 44 400 and 45 700 will be our resistance levels. On the other side, 41 600 support will be important.
