Post photos and testimonials from customers - which can be verified. You’re asking people to trust you with many thousands of dollars in computer hardware on a post. You didn’t post a link to your site as well, but it’s easy enough to get it from your email.
Your whois report gives nothing, but in a situation like this where you’re asking people to trust you, it’s odd not to make full disclosure.
And since your domain was only registered a few weeks ago, you’re just starting up with this “trust me, I’m gonna ‘watch’ your miners for you” endeavor. Do you have any miners of your own? How much skin of your own do you have in the game? Many here have a ton of money invested in their operations. I’d surely not trust someone with my hardware.
When you actually have something to sell, come back and try again. Until then, you’re gonna need more than a come on of “trust me…” to get folks around here to bite.
