Being a sci Fi fan ,I love the idea of alien intelligence and all the musings that go with it. That said, we need a lot more evidence before a near miss by a strange object will supply the proof necessary for the conclusion that it is alien intelligence. I agree with you Ed, that 2018 is going to be unusual to say the least. We are witnessing a paradigm shift in currency that is undeniably real. Who wins out between Bitcoin, Ethereum, and a host of others remains to be seen but this change is real and unfolding right in front of our faces. It is fine to be a skeptic, but blind nay sayers add nothing to the discussion. They are not steely eyed realist but actually timid people afraid of change. HODL everybody!
