Even since from the day it developed to till now we have seen it in incremental state.There will be a point when those users who purchased their coins at $1,000 or $2,000 per coin decides to do full or partial profit booking. If the demand is not very strong at that point of time, then the exchange rates can crash. This will trigger panic selling, which will pull down the prices even further. But I can't predict the level at which this will occur.
