The volatility in Bitcoin is an avenue for traders to earn money, this arrangement puts Bitcoin ahead of the Blockchain tech. thereby delaying global Blockchain adoption. Blockchain without Bitcoin, is it going to happen?
I really do not understand your question or what you mean by it! Bitcoin is a currency built on the blockchain technology therefor Bitcoin on its own is not a tech it is just a currency.
The blockchain is already used in some projects that do not have any cryptocurrency at all. Even people that do no like Bitcoin or cryptocurrencies still admit that Blockchain is the future and probably the most important invention after the internet in this era.
