If you're wanting to build your own miners for BTC, you're either gonna have to go to an existing manufacturer like Bitfury with at least $1M for an order of their ASICs, or come to an existing IC developer with about $10M (and around six months) to run you out your own custom design. Unfortunately the only "realistic" course - unless you have a whole lot of money you're willing to risk losing entirely - is to buy existing miners from someone else.
Interesting, ok great feedback thank you.
I'm not opposed to these options so long as profitability looks reasonably positive. I would prefer though to star with a smaller operation to test things out first, which leads to the "buy existing miners" option, however each time I do profit/loss analysis I seem to come up negative due to the reasons I listed above for this topic.
Have you purchased some existing miners before and came out profitable despite the list of expense items I listed above?
No matter what coin you are mining it all boils down to just 3 things:
1.Cost of your electricity.
2 & 3.Cost of what it takes to deal with the heat and noise.
As long as income exceeds cost of those 3 things - mine on.
Thank you for helping, I'm grateful to be chatting with people actually doing mining
Have you found that you were able to remain profitable regardless of mining difficulty increases?
How long have you found your rigs remain profitable before they are surpassed by superior technology? 6mths? 12mths? More? Less?
Have you factored in labour time requirements for this or has this not been physically included in the expenses section of COGS?
