You may think crypto is trending, but actually it isn't yet. The only thing that is trending, is people understand that Bitcoin exists. Outside of that, people know squadoosh. How you know this is because people know Bitcoin, yet when you mention Ethereum they look as if you are from another planet. Couple that with the fact most people don't understand the basic fundamentals of cryptography, and how these currencies work, the average person is not knowledge yet about crypto. Therefore, I say Bitcoin is trending and not crypto. Although I believe that will change in the coming years, likely after the 2020 halving.
