BTCUSD Still expect $3200 to hold and the trend to continue up

The $3000-3700 area had the most important volumes in the past fews days but not only, in the past year as well.
If you zoom in the chart you will see it was buying happening, and the main transactions happened around $3200 area and $3400/3500 area.
Therefore I think important market players entered in this area and will not let the price go further down.
