Scam is too much of an accuse against paper money even if we know that their future can be limited. Don't forget however that still in our day fiat is the major trading globally as to many economies are floating around paper money. The other part is that Bitcoin is coming hard and is trying hardly to get a reputation of a global use currency with mass adoption.
Yeah I think so, we still use paper money for spending, and it's still worthed. why do we say it's a scam? the problem here is
why does this paper have value right? as long as the paper has a rate (according to their economy) it is legitimate as a means of payment.
