[" Jdietz "]

I have been fascinated by Bitcoin since I first heard about it
and now a thread has appeared on a forum in Thailand  where I live for expats.
Could somebody please comment on the accuracy or otherwise
of the statement made by the member named " Jdietz " who are you will see
in post number #12  claims that " people are selling their "mining rigs"
and that Bitcoin is nothing more than a bubble or even a pyramid scheme.
a few other contributors have made similar remarks and I think they need to be educated

here is the link:-
