What can be written off on taxes?

As a cryptocurrency and finance professional, I'm often asked about tax deductions related to this field. One common query is: "What expenses can be written off on taxes for individuals and businesses involved in cryptocurrency transactions and investments?" The answer typically involves various costs incurred while engaging in crypto activities, such as mining equipment, trading software subscriptions, transaction fees, and professional services like tax advice or accounting. Additionally, for businesses, expenses related to developing or marketing crypto-based products and services may also be deductible. However, it's crucial to consult a tax professional to ensure compliance with the complex tax laws in this rapidly evolving industry.
