Everyone is hoping that bitcoin will continue to rise in price indefinitely.
Bitcoin wont keep on raising forever,since this is a new form of currency and there is a huge interest in it and so is the reason the price is rising.
They look at the growth from $0.003 to $18000 and think that bitcoin is unstoppable
It is a fact that the price grew this much and this is not a dream right.

So what is the issue now,you missed out when there was an opportunity.

Is everyone buying into a dream that is too good to be true? How can bitcoin go up over 6 million times its original value without approaching a bubble? A $100 investment in 2010 would be worth $600,000 dollars! Where the heck does that "value" even come from. Bitcoin produces no revenues and provides no tangible assets. How can a $100 investment be worth $600,000 after 7 years? You can't just make $600k from scratch without there being losers involved. So who are the losers going to be when this wild ride is all done?
If you hold fiat currency and once that bubble burst you will be having color paper to keep yourself warm,that is a good idea right.No one is forcing anyone to buy these cryptos and what is the issue here,the fact that any asset gets its proper valuation when people are willing to spend money for it
and it is not like fiat currencies where government can print out any amount of notes according to their wish and in the case of bitcoin,it has limited amount of coins and it cannot be duplicated and that is the most important factor.
