Is trading haram or halal?

Could you please elaborate on the question of whether trading is considered haram or halal? I'm particularly interested in understanding the religious and ethical perspectives surrounding this topic. Could you provide some clarity on the views of different religious denominations on the matter of trading? Additionally, I'm also curious about the practical implications of this classification, especially in the context of cryptocurrency and finance. Would it be possible for you to explain the potential risks and benefits associated with trading from both a religious and a financial perspective? Thank you for your assistance in clarifying this complex issue.
