Support and why it's important
Support shall not be broken!
Support is the layer on the bottom of where the price is at that certain moment in time, so if that were to break then you would slide all the way down to the support that was there before that. Supports are there on all kinds of time frames, however support that is on a higher time frame means more than a support on a lower time frame. Let's just take a look at a chart of Steem for example. All the white lines are structure lines, they are both support when it's lower and resistance when it's higher than the current price.
What happens when support breaks?
When a support breaks we go back down to the support that was there before that, however this is not always the case it can drop even faster that it skips right past previous support and looks for major support. Remember what I stated above, the higher the time frame the support is on the stronger it is, for example a daily support is stronger than a hourly support.
