These economists should leave bitcoin alone. They should take time to talk more about the downside of fiat currencies. I won't need to bother myself with this kind of negatively because it can never change my belief regarding what bitcoin is capable of achieving.
Economists always observe and comment on bitcoin from the negative side, that is, bitcoin is anonymous. Always associated with money laundering, terrorist funding and even drug businesses. While the positive side of bitcoin is rarely discussed. Observers forget that the digital age has arrived, and bitcoin places itself as a digital currency, where transactions are easier and more convenient.
