Salam sayyed,
I have another question on my mind. Cause recently the bitcoin, ethereum and litecoin are a lot in the news because of how fast the currencies go up. Is it Hallal to buy a little bit of such currencies knowing that the currency may go down. So is it investment or is it considered gaming.

Walaikumussalam brother
Aagha e Khamenei has not given any verdict on this issue I'm waiting for the reply once it will be received inshallah I will share with you.
But according Aayatullah Sistani it is allowed
