Assuming you bought Bitcoin because you heard/think it will increase in value, why would you want to spend them to buy something with such a valuable currency? I am also assuming this is not your only savings or have drained your savings account and are counting on Bitcoin to increase before your rent is due. Just one person's view. D
Many people working far from thier families and they used Bitcoin currency to send money for their love ones and they told it is past and secure a reliable source I heard.
