The short - term volatility trend will continue until the end of

March 1 is a time node. If we look at the trend of this wave, although there has been a sharp adjustment, it is still basically an upward trend. Will it be a downward trend next? This is the problem I have been worried about, if there is a downward trend here, it will be a more dangerous signal. So then we have to be vigilant. From the trend line, the channel and support line below the role of the current is intact, but once the break below can not be recovered, the bulls need to strictly stop the loss; The same problem for the short, up means breaking the trend line and track. At present, the support and pressure are set at 3710-3910. In the short term, the operation advice I give is still to wait and see, unless there is a clear signal of change. While this is the BTC's trading advice, it is equally valid for most targets.
