To any of the "he gets rich" screamers - revenue of this venture so far: about -20.000eur + 4 Months of Work.

Not that those people will believe any of my words.
Very sorry to hear this burnin, but you could've sold in-stock bitfury boards (aka no more problems like bitburner boards) and make up for those money instead of letting cryptx to get a piece of your money(many people stated that they were ready to buy 10+ boards with a reasonable price). I will make my donation sometime in the next month for the awesome BitBurner boards.
