What I was trying to say was overall the technology is not a bubble. I am the biggest believer of blockchain as explained in the video. However, as people wihout knowledge of blockchain and people just trying to make money are investing in bitcoin, there will be more crashes like the one we are having now which is similar to a bubble. In the long run however I am a massive fan of blockchain and see the price about $30-$50k by end of the year. Thanks for your comment and lets keep sharing the blockchain technology to the world.
