Bitcoin ban: These are the countries where crypto is restricted or illegal

Bitcoin has been controversial since its beginning in 2009, as have the subsequent cryptocurrencies that followed in its wake.

While widely criticised for its volatility, its use in nefarious transactions and for the exorbitant use of electricity to mine it, Bitcoin is being seen by some, particularly in the developing world, as a safe harbour during economic storms.

But as more people turn to cryptos as either an investment or a lifeline, these issues have manifested in an array of restrictions on their usage.
