Be careful with people in this thread. It looks very likely that there are scammers posting here. Baikal only just released first batch of cubes and only sold one per customer so people who say they have multiple cubes for sale are probably lying.
i think the same things...
i have chatted with the official baikalminer customer care, and he told me, who now are out of stock , and they sell just 1 cube for user...
They also have another channel that they provide, without limit, to the suppliers in Shenzhen. These suppliers work to lock-in pre-orders. It's a risky business because the suppliers can change their price without notice - unless you give them $180,000 at once. Look at the S9s and L3s by BITMAIN. They go from $1000 - $5000. There are a lot of factors, not the least of which is price of the coin/electricity/difficulty.
If you buy from a 3rd party site, check the registration on whois and see that they are a registered business. I "bought" my first S9 from a company that was fake. I reported it to BITMAIN and the BBB. The site is now down, but I'm out the $800.
They sell one per retail customer and more to suppliers in China who then resell here.
