We cannot predict the future perfectly, but I guess Blockchain and cryptocurrency is the next big thing since the advent of the internet. People dismiss bitcoin and other cryptocurrencies altogether without further understanding its implications to the future society. Furthermore, bitcoin is a continuously developing concept; it evolves very rapidly and there is a growing number of core developers now. We can't really judge something's future based on its present state. As of now, people are not seeing the complete shape of bitcoin technology because it doesn't take any shape yet. Thus, judgment is still too early.
