Possibly not a scam but they have now released press about 3 or 4 different ASIC units without one unit on the market. Granted I know Obelisk have done the same but it seems to me these guys are looking for funding to build the technology to do what they say first. I just don’t get how they can be given so much credit without proof?
They've got a representative from MyRig (Yoshi), which is a reputable and legitimate site that I've bought from many times and offers repair services based in Colorado (paid, but better and quicker than Bitmain's for Americans), and they certainly do have proof that at least their BTC miner is legit. Their Twitter page and Youtube channel shows proof of their miners hashing, including the B29 (which is a bit dated), just seems they haven't delivered miners yet, though they seem to be near that step. At the very minimum they've got miners that actually work, so their miners aren't vaporware. Once we get towards the end of March and April we'll start hearing more from Halong and customers that receive their ordered miners.

https://twitter.com/halongmining?lang=enAnother way to look at it is this: most all miner manufacturers sell preorders nowadays, and taking a short look at all the upcoming CryptoNight miners confirms this (it's been true for as long as I've been in mining). Halong's doing just that, and they've provided at least some preliminary proof their miners are legit, and they're backed by a trusted service.
