Blockchain and Bitcoin are two totally different things. Similar to a necklace made of silver, Bitcoin is made of the blockchain. The blockchain is a technology for making immutable networks like Bitcoin, which makes blockchain more powerful! And blockchain is the present evolving topic. You can’t have Bitcoin without blockchain, but you can have blockchain without Bitcoin. That being said, most people talking about “blockchain technology” want to be centralized, private, permission, limited, weak tea versions of Bitcoin so they can control it. They want this because they fear the openness of Bitcoin and because they’re late to the party. They hype their version, claiming that their version will be better, more secure, etc. In reality, they’ll perform fine until something goes wrong and the whole system will come crashing down. By the time they realize this it’ll be far too late. Nowadays, blockchain is so evolving that each and every transaction are made by blockchain only. It's not the end, It's the sign of big change in security.
