I have to agree that Hashcoins / Hashflare started with a somewhat shady business.
But have improved greatly since.
Can only report positive about Hashflare so far.
Started with a very small hashrate and later bought a huge chunk from an other user for a nice discount.
Hashflare transfered the power to my account after the seller confirmed the payment.
A nice service and no risk of getting scammed. Like it.
Meanwhile ROI'd several times.
Can not say if there is 'real' hardware mining or if it's all just a big bubble. Tried to confirm it with switching pools and watching their hashrate, but there is to much fluctuation and i don't know when exactly they switch. (guess all 24 hours).
But let's say it that way:
There are a lot of pictures from the Hashflare Team. Including several from Bitcoin-Conferences over the last year.
So it's absolut possible to meet them in person. Which is imho a very good sign.
Plus, just found this:
https://www.youtube.com/watch?v=OFx4oI3eZ4ELooks like this is the Ethereum Mining Datacenter. Can someone translate?
So for now i can say: Yes, i trust them. But of course only with money i can afford to lose.
As usual, be carefull.
Edit:
there are also multiple Webinar videos showing mining hardware.
I have not looked at all and can not estimate whether there is actually real hardware to see.
But see yourself on youtube "Hashflare webinar"
