With that sort of question, I don't think you will be getting the answer(s) you would want or would like to see.

But the answer I will give you is that applying 'blockchain' to everything does not make sense. Best stick to payments or domains instead.

Let's see at least some replying with an absolute response and sweeping the brush on everything, or over-generalising and scanning anything that has the word 'blockchain' on it and screeching on every related blockchain post.
