I think in all cases people have to be smart with their investments and not put all of their eggs in one basket. I think long-term, the crypto's built around platforms like Steemit will outlive those purely for trading. There will simply be more value in having a system instead of just a coin. However, as long as supply and demand maintains and demand doesn't dry up...I don't see the industry as a whole just falling off a cliff. People see that there's too much money to be made here. I don't think blockchain technology is going anywhere. Certain coins may die though
