Many Muslim will come of the view and worried about this question . please give suggestions
Good question,the same question was asked to me by a friend of mine.
Bitcoin is just a currency and it is made of technology to prevent hackers from hacking in online transaction.But people use its demand to make profits it is just due to skill nothing to worry.If you are buying bitcoin with money which was earned by halal way then your bitcoin also halal.
Don't mix technology with the religion,I hope you understand now.
