I make use of Bitcoin as an investment and not as an currency because I am not interested in buying things with my Bitcoin. If I want for need something I pay for it with normal money.
I just use Bitcoin to let me make some more money next to my job.
Yes if possible, deals only in fiat in those things in real life and let just bitcoin saved in everyone's wallet waiting for the right time to sold.
Income from daily job + bitcoin earnings is really a wonderful combination that can help us support our financial needs.
