Our world changes constantly and if you want to move with the times and to progress along with the rest of society you should accept bitcoin. No problem in using usual money as well as digital currencies if it gives you comfort. If bitcoin disappears it doesnt mean that fiat money will grow.
The best will be to use blended system...But unfortinately, the main use case for cryptocurrencies is speculaton,users use bitcoin strictly as an investment. We need more bitcoin in real economy,the tendence for daily purchases.because in the digital realm it is used only in large businesses,small businesess don't use it as a payment method,therefore there is one question-Is there is a need for such a thing?...Its right today they are creating the tendences but its not enaugh.In additional,Cash also offers two additional advantages,it allows us to be precise about how much something is worth and let's us use numbers to talk about value...and at the same time bitcoin also gives advantages,That's why I think it would be better for everyone to use blended system.
