[Hello there,]

Hello there,

/!\ Please forgive me if I'm not in the right section, I searched, but it's kinda messy out here for this specific type of question, so I'm gonna go ahead and write my post, move it if it's not fitting your terms.

Let me be straight:

I'm looking on creating my own ASIC Scrypt Miner. Why ? Profits. I know, i know, it's maybe not the best motivation, but, lets be realistic, I'm here for it ahah.

Since i got into this miner thing, I realized that it was almost impossible to make real and efficient profit from GPU miners, hardware are expensive, such as the electricity cost. You can eventually make some profit out of an old (and used by Chinese) ASIC miner. Cheaper hardware, cheaper electricity consumption, and a High Hashrate. So unless you have several non overconsuming machines, and a good electricity prize, it almost impossible to make more than 3-4k a year.

Since all 10TH/s+ ASICs BTC miners are Scams, and as Bitcoin mining difficulty is increasing a lot, it is almost not profitable anymore, or not for very long. You'll soon need 50TH, to get what you get today, and honestly I don't really see where it is going from there.

So why am I talking about BTC which is a SHA256 hash, while i said I want to build my own ASIC Scrypt Miner ? Mostly because, it might be the only way to still make a lot of profit from the cryptocurrencies. Scrypt ASICs do not seems to be built with the same efficiency than the SHA256 miners, which is a shame, since the only thing that these machines are doing, is pure hashing. So why can we make 14TH/s machines for hashing SHA256, while we can't make more than 500MH/s to hash Scrypt values ? I'm sure it is doable.

First if we compare an ASIC to a GPU Miner, if we get reed of that Windows OS, replacing it with a Linux (Debian for example), it could roughly increase or ratio. But it's still not enough. So Windows is consuming far too much ressources and i understand why, but having 3/6x a 8GB GPU, and still not have enough power to produce more than 500MH/s, are you kidding me ? There is something going wrong somewhere. A computer is a super calculator, created to solve complex math in milliseconds, so there must be a way to have a correct balance between the power of your GPUs, and the Hashrate generated.

Honestly seeing 4x4GB miners, only Mine few MH/s, is kinda misleading, because GPU Miners would have more power than basic ASIC Miners, but would still Mine less ? What is an ASIC doing better than a GPU setup ?
The main role of the computer is calculating, nothing more, so why is it so tricky to have a good Hashrate?

My second question, what is an ASIC made of ? (I already have my leads, but i just want confirmation from someone who owns one.)
I really want to go further investigating this aspect of Cryptomining, and maybe come with a new product or a new setup.

I greatly thank every people joining this thread, and to some time to answer my questions.
THANK YOU.
