Hey OP, if you don't want to buy Bitcoin any longer then it's your choice ,that won't make others to stop buying it, there are lots of people who will continue buying it and everyday lots of people keeps getting in.
Moreover FYI, what you have said here is wrong, of course I have heard about the 51% attack or whatever they call it, but that's not enough reason for me to quit. People keep on imagining things that are never even going to happen. A lot of people come up with these as a way to discourage others from taking part in buying Bitcoin.
This guy is an Ethereum shill. Guy didn't even know that the Chinese government is not pro Bitcoin itself. The Chinese government in reality continues to monitor and track miners because they are against it. There are still many Chinese miners out there, but they are the most open minded Chinese unlike their traditional government rules.
