How are crypto assets taxed?

Could you elaborate on how crypto assets are taxed? Are they subject to the same tax rules as traditional financial assets? Are there specific tax brackets or percentages applied? Do the tax regulations vary by country? Are there any exemptions or deductions available for crypto investors? What about long-term and short-term investments? How are capital gains taxed? And finally, how do crypto exchanges and wallets factor into the taxation process? I'm particularly interested in understanding the complexities and nuances surrounding the taxation of crypto assets.
