Markets were in red during last 48 hours. Nothing to worry about since it is not the first attempt time manipulators trying to take coins from weak hands. Blue lines are current longterm support zone and lower it is unlikely that btc could go. However, I won't recommend using margin trading these days. Due to possible short term shots down outside of support zone. Targets for long are 6400, 6525, 6750, 7100, 7480, 7602.
