I don't know what idiot would think bitcoin is "not" real! bitcoin is a
real currency or you can call it a payment system if you want but it is all real, and it has been real for nearly 9 years and it has been processing about 1-2 billion dollar worth of transactions every single day for the past year and half that last year.
it doesn't get any more real than that!
as for bubble, I admit I also have the fear that bitcoin may be in a bubble but then I look at the charts and see all the corrections, the drops, and the 30% dumps that happen and then look at all the money that is pouring in bitcoin from all around the world, from different countries (
