If you set aside the pump and dump profit trading monetization thing in alts, what really matters is that we keep building on and enhancing the work and contributing and evolving more and more tech. Because this stuff is important, and it will change the world one day, irrespective of speculative pricing.
Yes if you concentrate on the tech, usefulness, simplicity(for users ease of use) and ability to adapt to emerging markets/needs = lasting value will come from that, rather than these quick pumps.
