why do you even insist on separating the two from each other?
it is like asking which one would survive longer, cars or combustion engines! bitcoin is based on blockchain technology and it is the one that introduced it to the world. bitcoin is also the one that is improving this technology and as the technology grows bitcoin grows and vice versa. they are not separate, they are one thing.
Thanks for your words.I am not insisting to separate them.I am just sharing what I understand.I agree with you upto some points because currently Bitcoin is dominating whole crypto world. but same time there is question.:
How this dominance of Bitcoin remain as it is or it grow with time???
On other hand Blockchain is a technology and everyone (Govt. and all kind of business houses) are willing to adopt it but less keen to adopt Bitcoin.Now in that case will Bitcoin still survive???
