Do you think ever-increasing centralization is a cause of concern? What would be the impact of tightening regulations over the entire crypto/Blockchain space? Will it still be able to survive? Your input will be greatly appreciated. Thanks in advance. 
Some who dont like centralized will slowly get away from blockchain. But centralization only restrict only those scammers and law abiding citizen, whereas they cant completely do their scamming activity. It doesnt mean cryptocurrency industry will tremble in chaos or panic, but only those who are doing malicious activity.
