Point.2 I am a muslim and can assure you that it is not haram in islam if you use it for preserving wealth or as an investment but it is when you use it For Gambling or other haram stuff.
I still disagree, the reason why Bitcoin is haram because people think that as high risk investment, not about the usage. It's also not backed by gold or fiat, which is another reason.
I'm sorry but are you a Muslim? If you are not then I am sure A Muslim would know better. But if you are a Muslim and don't have knowledge about this matter I suggest you reading this article.
