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 would choose both. Why? because both have its own advantages. I use cash so that my money is safe and can be directly used to buy things, and I will make bitcoin as investment vehicle
