Price crash or Price rally.It doesnt matter as long you do know on how to utilize these movements to make money then this wont really be an issue.

No man can predict on whats ahead or what would happen into this speculative market because price can move in least expected manner.Therefore, you should really be prepared
on what are the things that would be on the way.

If you are a holder then this issue wont really matter since you do hold for more years to come but for shorter? then this will really be a hard one.
