I think the statement is overall positive as it recognizes the legitimacy of bitcoin as an asset. Even though nothing truly backs the euro or the dollar either; trust is what has maintained their value as they have printed money and issued debt to maintain their economies. Ironically, bitcoin sidesteps the need for trust by decentralizing the network. Thus, the value is in the limits imposed by the network whereas no one group or person can control the supply of bitcoin and therefore cannot go against the willbof the users.
