i honestly can not think of anybody who does not benefit from bitcoin! even banks that some people say are against bitcoin or bitcoin is against them are happy about bitcoin. not only bitcoin introduced blockchain technology to them to improve their business but also it has opened up new ways for banks to make money. banks are in fact making a lot of money because of bitcoin, all these traders are using banks to handle their money transfers and there are lots of them
Well that's one kind of people. There are others who don't since they are afraid to try new things especially the old ones nowadays since the impact of the news they heard in TV.
many peoples think that BTC is a fake currency thats why some peoples are against BTC.
