I am reading tech news extensively on different platforms. HN is also a great source. I assume, you would like to profit being ahead of the flock. The trick, though, is to make a judgement of what will come out as a disruption. Bitcoin, before it was cool, was just a crypt currency. Something new, and something that except for few, no one understood. And yet, it became what it is today. Some were lucky because they just decided to try it, others because they made a sound judgement based on experience... and yet some made a big mistake.
