Speculation is what makes the price interesting and give hope to investors, Yes this is true there's no assurance price will increase or decrease but one thing certain about bitcoin is that we must get either increase or decrease in price. As for the demand I know is somewhat not too certain as well because despite a high volume of demand a common news can easily influence the market and shrimp holder or even crab holders would panicked and sell of immediately the supply will supercede the demands.
People who do panic in cryptocurrency and mostly when bitcoin price decreases, is who doesn't know the rudiments of bitcoin, so therefore I believe that bitcoin have to do with fluctuating in price, so if you are no conversant with the price, definitely you will panic, as we have known the tactics or the system of valuations, so we don't need to complain of bitcoin decrement whenever it happens and sell out our bitcoin under panic or fear, so that's why I said that it's only someone who has experience multiple times of bitcoin price rotation can endure when the price becomes physical unbearable, and secondly, its the negative speculation of people that motivate new investors to sell out their coin.
