Thank you for your comment.
In my opinion Bitcoin is shit (from use, technological and bubble perspectives).
Blockchain is there to stay, not Bitcoin.

I agree entirely, if I look at it from a purely financial perspective in terms of a business enterprise which is what it is for the miners then the ends don't justify the means. The concept is good, but the business model sucks.
