Before anyone else jumps on this, remember that there's already another Siacoin ASIC being shipped from
https://obelisk.tech/ They're already doing batch 2 so the hashrate might already skyrocket before these Bitmain ones even ship out.
Uhhhh..... and when are these non working prototype obelisk being shipped?
Who knows. I think the last thing I read was that they were hoping to ship them sometime in the first half of this year or something. I just don't want anyone wasting their money like they did on the D3 and all of the BTC ASICs from years ago that were useless before they even left the factories.
The Sia dev is talking about possibly forking just to keep Bitmain out lol. https://www.reddit.com/r/siacoin/comments/7r4spy/dev_team_thoughts_on_the_bitmain_a3/Uuppsss .... currently on block 138893 and will be forked on 139000
I hope I received before the fork and got ROI

I think that fork was just to address the difficulty bug but I don't know for sure. Right now, I think the only thing you have to worry about is potentially too many A3s driving the difficulty too high to ROI, but I don't know how many of them were sold.
I will directly mine as soon as I receive it ....it's a race .. ha ha ha
