I think so too. There will be a big collapse because the majority of the people who buy bitcoin is purely for speculation only. I think the majority not fully understand the mechanism of bitcoin. They just see it keep going up so want to profit from it. It can only go up if more people accept to pay higher price for each coin. Until certain point when the price is too high enough, many people will sell it to cash out to realize the profit and avoid the risk of loosing what have been earned. That will make the price drop fast. Other people will see that and do the same because the believe "the collapse is happening" and it drop faster,...
