i think btc found support around 18500 and 19500 . there is no other major support zone, if this support is lost there is no doubt btc will go to 12k quickly, and will take altcoins with it. there is no clear reversal sign yet but i think long positions can start to be openen here, as long as it stays above this support, other wise sell at any signs of weakness, and wait for another support entry area. if bulls can maintain it it could consolidate around here and move to the 28k target first , so keep an eye
