The price of bitcoin is regularly fluctuating, so you might get $100 worth of bitcoins now, $50 or $200 worth of bitcoins tomorrow, who knows? So, do you prefer a currency that is more stable, like cash (USD, EUR...), or do you treat bitcoins as a currency, for investment to let it grow?
State why you prefer your option.

I prefer my money to be in cash,but my savings to be in bitcoins.
I can`t invest all my money in bitcoins because i have to spend for food,gas,electricity,bills,taxes.
I can`t use bitcoin for that.
