Thanks Augusto. Is there anywhere that lists real ASIC manufacturers vs SCAM sites? Would be a great resource because the ratio isn't very healthy.
in short, no, not that I know of.
in practice, there were two useful threads until a few weeks ago, the scam list: https://bitcointalksearch.org/topic/the-scam-list-366659 , but this has not been updated;
and the newbie guide to asic vendors https://bitcointalksearch.org/topic/newbie-guide-to-asic-vendors-403459 which has a slightly different intent.
a great web resource is http://bitcoinscammers.com/ which shows some of the latest scams
and nothing really takes account of the new wave of avalon clones and bitmine chip machine makers, some of which are real, and some scams
so there is something for someone to do (hint)
