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 know there are some people who said Bitcoin is halal and haram, but from what I know, if it's debatable between halal or haram, better to count it as haram instead.
There are 3 main reasons why cryptocurrency like Bitcoin may be considered haram:
It’s a high-risk investment similar to gambling
It’s used differently to money
It’s not regulated by governments or financial bodies.
For example, a 2019 fatwa by the Syrian Islamic Council explicitly declared cryptocurrencies “like bitcoin” to be ḥarām. They listed many concerns: crypto exists only digitally and isn’t backed by gold or fiat, it’s not regulated by any bank or state, and its prices jump wildly, raising questions about whether cryptocurrency is haram. This makes crypto “inherently high-risk,” they said, which is a concern for those evaluating if crypto investment could be halal.
