I think both the bitcoin and blockchain can survive in the long run... As both have some key features that can transform the world... Also, with a greater audience and mass adoption, both will have to work concurrently.
Yes am also agree on this both Bitcoin and blockchain will survive long run. Blockchain is the technology using which lot of crypto coins are invented and came into market hence the growth and demand for blockchain will be more in future. Blockchain makes market ease,competitive and have lot of features which is required for the crypto market.
I think blockchain can exist for a long time because blockchain is a useful technology in many different fields, many countries and companies have started to explore and use this technology, and with such acceptance and dissemination, the blockchain will certainly have a place and an important role in the future. But with bitcoin, I think not, although it is the leader of the crypto and is widely known, but everything still can not change the fact that bitcoin is still an investment, and investment is only temporary, people will soon replace it with another investment
