Since Bitcoin appears to be neither suitable as a payment system nor as a form of investment, it should be treated as neither in regulatory terms and thus should not be legitimised. Similarly, the financial industry should be wary of the long-term damage of promoting Bitcoin investments - despite short-term profits they could make (even without their skin in the game). The negative impact on customer relations and the reputational damage to the entire industry could be enormous once Bitcoin investors will have made further losses.
