Hi,
Sorry, it's not that good of a deal IMO, even if it's in hand.
220BTC for 500GH/s works out to: ~$27K for 500GH/s.
You can buy a KnC Jupiter that will outperform this for $5K *and* it should arrive in November.
Its 220 BTC for 1 TH/s mate, ~27 K for 1 TH/s
That's still not so great when KnC charges $10K for that hashrate shipping in November, and HashFast charges $7K for B2 1.2TH/s (Nov/Dec).
If you really must spend $2.7K on near term hardware you'd be much better off with the Bitmine at-cost GB I have going on at the moment. The thread says its CLOSED but we're still taking orders that will shift to a Round 8 on the same Bitmine Rig (extra modules) or into Round 7 shares for shares that were reserved but weren't paid for.
$2.7K would net you 38 shares in an at-cost GB I'm currently hosting (
https://bitcointalk.org/index.php?topic=308512.msg3321223#msg3321223 ) for something like 304-456GH/s depending on how well turbo overclocking goes. For ASIC miners: Our business insured professional hosting/management rates at 2.75% are the lowest around, bar none. The hardware won't arrive until late December but you'd be saving a ton of money.
Giorgio from Bitmine is on the up & up. I've checked them out myself and was helpful in pointing out the need for LinkedIn links for the company's leaders on Bitmine's site.
BTW, I also vet new miner hosts and Group Buy Coordinators for free if anyone from Asia would like to join my GBEC / Miner Host Matchmaking services. I don't have any representation from vetted miner hosts or Group Buy Coordinators in Asia yet, although I know that several co-op members live in Asia (we have 4 continents & 2 island chains represented). I've vetted 8 or more GBCs and/or miner hosts so far.
