Is it possible to build a BTC miner?

[futurepast1019]

Wait for Bitmain S9s to go back on sale, and buy 750 of them. Alternatively, you could purchase 1700 AvalonMiner 721s. You’ll need a building to put them in, power supplies, adequate cooling and more than a megawatt of electricity.

Yeah but if you buy S9s you'll have a couple months to get your building ready before they arrive.

Hello,

I'm new to bitcoin & the forums. I've been searching for this in the forums, but no luck yet. I've been wondering is it possible to build a modern miner scratch from parts? And if so, how difficult & what would costs be?

Thanks for you help.

Bro, you'd better take a part in bounty&airdrop. Start with that. Mining is for high professionals maniacs=)

That would be great if we coud build our own miner, but it's just impossible.
Miners have such system features that make it impossible to build that system in primitive conditions.

The only part that's not relatively straightforward is the ASIC itself. Let someone with millions of dollars do that part, then talk him into selling you some. And then make a miner around 'em. It's not too bad if you have a background in electrical and computer engineering and a good programmer or two at your disposal.

To maximize your mining potential higher model or the latest model in graphic cards is the best way to start with.  You can build one from scratch but if you are planning to use out modeled graphic cards, you might be ending with a higher electricity costs yet less in bitcoin mine.  Search one in the internet what is the latest graphics cards you can use to mine with...

GPUs have been irrelevant in BITCOIN mining for four years. You've already given that advice in this thread and it's still just as irrelevant.

The OP said BITCOIN miner not Piece Of Shi* altcoin miner.
As Sidehack and far too many others have had to repeat here over and over GPU's will not work for mining Bitcoin. Period. End of story.
