The psychological barrier of $70,000 is the first level you should watch. In the past, sellers have tended to intervene in this area as a point of resistance. Considering the momentum thus far, breaking through this level may set off a rapid upward move that could result in a new all-time high. As they get closer to this level, traders should pay particular attention to volume, as it has the potential to either halt the rally or confirm a more bullish continuation.
