Yes, he did his best and is just sad that Yifu never full filled his part of the deal. We thank Bkkcoins for all that he has done for this
industry and the community. I am sure he got the skills to do and assemble any asic chips, other than the Avalon Chips, surely they
will be other vendors selling their chips soon.
ASIC that operate at current edge of technology (28nm) may solve the problem. The problem with Avalon was it was outdated before it was delivered. After even ASICs will operate on the edge of what is possible, the difficulty will stabilize and it will be worth making a custom board design. Same has been seen as GPUs were operating on the edge of what was possible. Constant (...even fallig) difficulty, but mining is also less profitable then. I think this will be the right time for development then. Everything else will outdate after weeks. (...see Bitburner)
