I needed to buy and have hosted a few Bitmain S19A Pro 110Th miners.(since my energy cost is not the best and I'm essentially maxed out on a 200Amp panel with Bitcoin / Altcoin miners. Let's not even get into the sauna that my mining room is....
)So I started looking around at ASIC hosting companies that also sold hardware like Compass which seemed too big for me and ended up selecting DelMarVa blockchain http://delmarva.io.
I initially purchased 2 x S19A Pro's with hosting and maintenance for a year using Bitcoin as my payment. Honestly it did scare the living shit out of me sending that much coin to a company I had never dealt with before but all I can say is that as of this point I am so incredibly pleased with the service and responsiveness of their company and owner Matt Harris.
Matt personally reached out to me during the entire purchasing, hosting and configuration process clarified the wait times and explaining his companies ongoing electrical grid growth. The end result is that I had my 2 x S19A Pro's online in no time and they were an absolute pleasure to deal with and made it ultra simple every step of the way.
I am now in the process of adding 2 additional S19A Pro units and due to their incredible passion for BTC and personal touch they have my business going forward.
If you are looking for a host that does it all I can personally recommend them given my incredible experience.
Happy Mining!
