I agree that holding is important from an investor's point of view but as far as the growth of the entire ecosystem is concerned, one should also spend some amount of holding to ensure the momentum of coins within the ecosystem. I have always believed that movement is a contribution to the growth and hence, I try to spend my 50% of the funds directly because Bitcoin is a payment system in its core and that how we should treat it in the first place itself. On the other hand, an investor can keep his holding active throughout his holding period.
