Bitcoin going up again and we know that Iran/USA tension is behind this.
"we" don't know that, "you" are making a guess. and my opinion is that you are very wrong. bitcoin doesn't need tension to rise! in fact if tensions were to grow and lead to a war there is a chance bitcoin price could fall. of course USD might tank too which would lead to higher bitcoin price versus USD.
If bitcoin keep up and down with such news, bitcoin ow worth can never be established.
bitcoin has been going up and down for 11 years and the overall movement has always been upward. this will remain the case until mass adoption is achieved. meanwhile there will always be short term drama that affects the market temporarily.
