So far I can buy what I need with bitcoin, but I need to convert it to conventional currency or real currency. Bitcoin is an investment and not a way of payment. Therefore, you really need to convert your Bitcoin into Fiat in order to buy what do you want/need to buy.
Yes I agree. To be able to buy things that we want to buy using bitcoin, we need to convert it first to fiat because as we all know, not all people and business owners are open to accepting bitcoin.
