According to:

Sayyed Sistani: According to obligatory precaution one must refrain from these transactions (i.e. you can refer to the second most knowledgeable jurist and follow his opinion).

Sayyed Khamenei: No response (i.e. you can refer to the second most knowledgeable jurist and follow his opinion).
It should be noted that in his opinion, it is necessary to observe the official laws of the country in this regard.

Sayyed Shobeiri Zanjani: If the use of such currencies is usually corrupt or illegal from an economical point of view, there is a problem with buying and selling them. (meaning according to obligatory precaution one must refrain from these transactions i.e. you can refer to the second most knowledgeable jurist and follow his opinion)

Sheikh Makarem Shirazi: Due to the many ambiguities that Bitcoin has, it is problematic (meaning according to obligatory precaution one must refrain from these transactions i.e. you can refer to the second most knowledgeable jurist and follow his opinion.)

Sheikh Vahid Khorasani: Buying and selling it is void.

Sheikh Saffi Golpayegani: It's forbidden and it's a type of eating up wrongfully. Allah is the All-Knowing

Sheikh Noori Hamedani: Engaging in these transactions is problematic (i.e. you can refer to the second most knowledgeable jurist and follow his opinion.)

Sheikh Hadavi Tehrani: Buying and selling Bitcoin is Haraam and as for other cryptocurrencies which do not have the problems of Bitcoin, it is permissible. (So his Fatwa about other cryptocurrencies is conditional to not having the problems of Bitcoin)
