i think if more people know about bitcoin then bitcoin can be popular and its not about bitcoin had a stable price, its about more people that will want to know and use bitcoin itself that will make bitcoin more popular
Yes its not bad and even its really good for me if bitcoin become more stable,yes bitcoin day trading may not be that popular if that happens but still users can do that in long term,and those who are earning bitcoin would feel much secure if bitcoin has a stable price.
