Don't make the mistake of making equivalence between Avalon and any other supplier. What Yifu and Ngzhang did was far worse than what any one else has done in this space by a very long distance.
Orly? What Yifu did is by order of magnitude more honest than what ScamFast did, and this comes from a both Avalon and HF victim. Eventually we all got full BTC amount back from Yifu, his greatest sin is destroying the dream of small miners to ever get in the fair mining game with the big boys. ScamFast deliberately lied with the intention to keep most of the BTC and never refund them in full to customers. Avalon is greed and incompetence, HF is pure scam, how can Avalon be worse?
You obviously haven't been around long enough to have any perspective on the subject beyond your own losses.
BFL promised false shipping dates every day for over a year to keep their pre order cash flow running. There was no batches, no attempt to give any realistic perspective of time to delivery if you ordered. Just lies from Josh and abuse against anyone who asked for refunds or actual facts. Hashfast has about 10 months to go before they come close to matching this.
As for Avalon, I calculate Yifu stole on the order of 250 000 bitcoins fron his customers by keeping batch 2 for himself. Simon has done a terrific job of promising things he can't deliver. He hasn't stolen what he promised to deliver as of yet.
