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?
You're wrong, Bitcoin doesn't stop blockchain adoption, investors are investing in whatever they think will be successful, companies are using whatever they think is going to benefit them. Blockchain is not getting adopted because it's a highly experimental tech, it doesn't actually solve many real world problems, is very hard to implement and has its own flaws. That's why tons of altcoins and ICO's have failed and are going to fail, not because Bitcoin is drawing undeserved attention.
