(~350 BTC lost just from my group buy only... no telling how much BTC was lost by all Batch 3 Avalon buyers. The number would probably be staggering.)
Ye if only they had offered a full BTC refund to those who wanted out, if only
They gave the choice between a limited time to claim a full BTC refund or taking delivery, with the understanding delivery would be swift. It was not, it took until the 2nd week of August for my B3 miner to arrive, by then the most valuable time had past. A BTC 102 machine that has only been able to mine BTC 59.18 up to today.
But let's not forget the mistreatment of the FPGA trade-ins, many people sent back (at sometimes great expense) their boards to China, but they never got a reduction on their Avalon orders. So they lost their initial hardware, could no longer mine with it, had to pay shipping and got ripped off.
Yifu basically ignored all of the complaints and keeps behaving like a rockstar. He made enough BTC to feel like a rockstar too. But seems to be unable to master running a company, dealing with customers and logistics.
Does that sound like a company one should do business with?
