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?
I think certain coins will be able to run blockchain to replace the role of Bitcoin as the leader of crypto currency. It could be ethereum, or any other altcoin that would manifest itself in the future. Only for transfer to fiat will already use other coins. Crypto currency is constantly improved and therefore you need to be prepared for various changes in the assessment of one of the digital coins.
