Blockchain Technology was driven to fame by its application on Bitcoin Gold due to its encryption that has been considered hacker proof. Bitcoin has been used as a reference to its success, providing a secure network for users.
The question however is, can blockchain succeed without bitcoin?
This is a difficult question because Blockchain technology is a great innovation but bitcoin seems to be the hallmark of Blockchain's success popularity.
I think Blockchain will survive because I can see many other sectors other than Cryptos adopting Blockchain technology to set up projects. However most of the new projects are using the Ethereum smart contract and so they're also affected by Bitcoin market volume and Ethereum.
When it comes to the future there are two points to remember (in my opinion):
1. Blockchain has been applied to various big companies, institutions, hospitals, pharmacy, etc.
2. Bitcoin will continue to exist. Because some countries have accepted its existence.
So, Blockchain will still exist without bitcoin. Bitcoin will also continue to exist.
